Hey guys,

There's a Far Cry 3 topic in the "Newer consoles" section:
https://forum.speeddemosarchive.com/post/farcry_3.html

I piggybacked that topic a bit, since it's supposed to be the same game, even though I don't have a console. Not sure if this still counts as cross-posting - if so, apologies.

I now have a draft run on the PC platform. It's a segmented glitchless attempt:

Part 1-2 / outdated videos removed - see the Youtube clips above /

I edited out all the long cutscenes, and those useless segments where the game just tells you to mash specific buttons. That ended up shortening the video by almost 2 hours. None of those are normally skippable as of the most recent version of the game.

I'm looking for improvement ideas if you can spot any: shortcuts, routes, skips, overall strategy etc.

Thanks.

Cool, will watch.

EDIT: Finally finished watching part 1... Everything looks very solid, some nice strategies/routes Smiley

Going to sprout some stuff:

Why didn't you just keep on flying to the ship Nostalgia and just land/fall on the ship?

In the temple at the end of the video, is it possible to throw a grenade/molotov or something in the rooms where you need to destroy the 3 planks/poles?

The big weapon you use for a big part at the end of the video has a really long reload time (And thus you can't sprint), maybe better to just stick to the previous gun you had? It does kill stuff quite fast though.

The constant jumping is really faster than normal running?

Maybe you do it in part 2 (Or perhaps it's not really that useful overall) but do you ever use recipes? Specifically Sprint Burst? You mainly use vehicles to get somewhere anyway so I'm not sure how useful it could really be, just wanted to point it out. Of course you would also need to gather some plants...

And something else I was wondering about. You call this one glitchless, what are useful glitches in this game?

In part 2 when you need to defend Willis while he's repairing the airplane, the other enemies seem to be triggered when you kill the first melee enemy? If yes, is it possible to keep the melee enemy occupied by making him chase you or something? Smiley

The other enemies will likely come anyway, though.

At 30:46, the knife throw takedown should be a bit faster.

Hey thanks for sharing, they are all valid ideas.

I know the answer to a couple of them, and I'll check the rest.

When you glide to a mission zone, a mysterious wind either blows you back from it, or forces you down into the water. The latter happens at the Nostalgia, so you have to swim the rest of the way, which is slower than switching to the jetski. There's one exception: I've managed to glide on top of the Comms Center, but sadly no time is saved there because the game insists that you visit the waypoints in the correct order.

The weapon choice is indeed a tradeoff thing: the LMG reloads slower, but you have to reload less often (since there are 100 bullets vs. 30), and it kills enemies faster. There are places where assault rifles are too underpowered (read: slow) compared to the LMG. In the end, for some missions the AK47 is sufficient, and for others, the LMG is better. However, constantly switching between the two, or getting the 2-weapon upgrade, also takes time.

I've measured jumping while sprinting to be about 10% faster than simply sprinting (except when running downhill - Jason keeps tripping and falling if you jump downhill). Jumping also throws off the enemies' aim quite nicely.

I wasn't looking for glitches much, although I've kind of stumbled upon a minor one since then: you can blow up Hoyt's chopper in Beras town, which eliminates a 40-second cutscene.

The knife throw doesn't help when the goal is to kill *AND* search the captains. There's a skill to auto-loot the body after a melee kill, which doesn't work for knife throws.

I'll see about the sprinting recipe, grenading the poles in the temple, and the kamikaze guy at Willis' airplane. Thanks!

When I was playing the game I always went through those 100 bullets very fast because the weapon has a high fire rate. But yeah it's a tradeoff thing, use what's best at that moment.

Yeah I figured it was useful against the aiming of the enemies. But so it's also just faster overall, cool.

Oh right, you also need to search those guys... I forgot about that. Love your routes in those "do not get spotted" parts Smiley

Some test results:
- You can sprint about 70% faster with the stim. It was a great idea! It's especially useful when running past enemies firing at you.
Challenges:
It takes a bit of time to harvest, make and apply the stims.
You need 2 blue flowers per stim and you have to swim for them. One suitable location is at the 3rd meeting with Buck where you jump into a lake.
It takes 3 skills to properly utilize them: Horticulture, and the ones extending the use of stims. They last up to 30 seconds this way.
These stims share slots with the medpacks.

I've managed to grenade the first set of poles. Another winner idea, thanks Void! The second set of poles however seems to be blocked by that tall wooden structure, besides you can only get close enough by swimming, but you can't throw grenades while in the water. I'll keep experimenting.

More soon.

I saved 18 minutes using new shortcuts and the suggestions in this forum topic.

As before, I've edited out the cutscenes from the video - including scenes where no skill is required, except to mash the buttons the game tells you to push. That shortened the video by nearly 2 hours.

I also found in the intro prison camp that whenever a "Throw the rock to distract the guards" sequence is started, you are able to jump.
Your ability to jump ends as soon as you successfully distract the guards.
Maybe there's a way to keep the ability to jump even after completing it?
Maybe you can find a way around?

AWESOME UPDATE: I just managed to get caught by the enemy WHILE activating the "Going through the window then Grant fucks a bitch up" cutscene at the same time!
Grant disappears and the enemy spots you but the game doesn't count it as a loss because it thinks you're in the cutscene!
Not sure what you can do from there but you are able to jump! Woot.

ANOTHER AWESOME UPDATE: Since the game thinks you're in a cutscene there are no barriers! You are able to jump over the wall and get onto the main road.
I think you might be invincible but who knows! I'm running down the exit path now that I have jump available to see what I can do.

EDIT: If you run too far you go out of bounds for the mission ;_;

EDIT AGAIN: It's really hard to get, I'm trying to record it but it's almost impossible ;_;

EDIT AGAIN AGAIN: Jesus christ, I'm still trying to re-get it. I've got it so people shoot at you during the cutscene but that's it. I still can't get what I got before.

EDIT AGAIN AGAIN AGAIN: So barriers are still there FYI. Also, I finally got it filmed, going to upload it now then share the link! Now you can all see what I did Smiley

I'm going to see if it's possible to freeze the timer for the speed boost effect. Or something like that. That would help.
Also, in a lot of games there's a way to stay dead and alive at the same time allowing for infinite health, maybe this game has that?

I've watched your videos. Great finds, keep up the good work!

When I experimented with glitches and possible skips, it seemed to me there were two obstacles.

One is the shortcut itself, i.e. avoiding cutscenes and fights etc.

The other is the waypoint system. Whenever I tried to skip a waypoint, I found that in most cases Far Cry 3 isn't very lenient. I could get around a waypoint, but gameplay beyond that typically wasn't possible. An example is the comms center on the Southern island, towards the end of the game. I could easily skip the action in the whole underground bunker. But when I got to the comms dish, there was no way to plant the C4 and I had to go back to the missed waypoint.

Your last video is similar where you can get around a waypoint and to the bridge, but the cutscene that would advance the plot isn't activated.

However your finds may very well lead to some neat skips so keep going Smiley

What would exactly be required for a 100% speedrun of this? On the progress menu there are a lot of things, but some just shouldn't be required for 100% (Trials of the Rakyat, and vehicles driven, mostly)

In Options > Handbook, there's a progress screen with the following entries:

Missions
Radio towers
Outposts
Relics
Letters of the lost
Memory cards
Trials of the Rakyat
Wanted dead
Path of the hunter
Supply drop
Story quests
Skills
Recipes acquired
Weapons acquired
Vehicles driven

Quite a lot... though that means there's a lot of opportunity for route optimization, i.e. once you're in an area or a particular route, you can take care of a lot of things there.

Edit: also, in a 100% run, I'm pretty sure you get enough XP to max out all the skills.

I've never been here or posted here before, but I might as well share my knowledge of the game for anyone who cares now or later, I've spent thousands of hours playing this game and I suppose I hold the RTA WR for it as well. This will just be glitches I've found that are/might be useful for speedrunning.

-Getting in front of Grant in the intro sequence makes him move faster, there's another glitch in this game I call prop surfing where you stand on the edge of a prop, it moves, and you ride it along as it continuously accelerates. In the second rock throwing tutorial, if you pass grant, then throw the rock, you could theoretically ride a crate to the end of the area and save a couple seconds (But that would also have a high risk of softlocking the game)

-In the intro area, you can get out of bounds in two spots as has been posted in this thread, but if you go out of bounds at the second spot (During the chase scene) and climb west over the mountain, then look out you can see a small far away island, that island is actually the interior of the cave underneath Dr. Earnheardt's house, by swimming to the back of it in an intersect between blue and green water, you get teleported underneath Dr. Earnheardt's house. From there, you're basically stuck underground, but if you can maneuver around enough to find a blue plant, you can harvest it and you will be pulled above ground, once you're up there you can go to Hoyt's island uninhibited. As anyone that has played this game will know, it is most likely useless.

-If you activate a radio tower just as you run out of range to activate it, or activate a radio tower and take a medical syringe at the exact same time, the radio tower will break and Jason will no longer be able to fall, allowing him to walk on air in a way similar to ISG from Ocarina of Time/Majora's Mask. Probably not useful.

-In the map tutorial with Dennis, the time required for the map to be possible to close isn't dependent on his dialogue, it's actually dependent on the time that passes after you select the Boar icon, if you select it immediately, you can skip 2 lines or about 10 seconds of dialogue.

-If you reduce your health to adrenaline level as you enter the crafting tutorial cutscene, you can use a medical syringe as soon as you make it, pulling you out of the crafting tutorial and immediately starting the Tautau tutorial, skips 30 seconds of dialogue.

-If you switch your weapon at the same time the "Outpost freed" cutscene thing plays, you can move freely during the cutscene.

-If a corpse is moving as you harvest it, and moves away from you, you can skip the harvesting animation, this doesn't apply to above ground plants, instead it just breaks those. It does however apply to underwater plants with you moving.

-In the underwater cave section at Dr. E's, instead of jumping off the cliff in to the water, you can simply jump off the cliff and land on the lower ledge, skipping the whole water section.

-In the section of the cave where you get high, once you enter the greenhouse if you get prop boosted (By the bottle on the floor for instance) and continuously mash sprint, as soon as you gain the ability to sprint you will do so at extreme speeds, this can be used to skip the bats that appear in the next section.

-In Pirate's Cove if the alarm is never activated, there are two pirates in the front area of the cave, and 3 in the back, if the alarm is activated normally there are 5 in the front area, and 6 in the back. However, if the alarm is activated just as you enter the mouth of the cave, all of the pirates in the front area will despawn, and only two will remain in the second area, which you can just jump over and ignore entirely.

-You can skip all of the checkpoints in the burning hotel and go straight to the last one and still have the sequence work properly, unfortunately I have not found a way to skip them without the use of a trainer.

-A guy named Stonehewer found a way to use the sliding door inside of Willis' house to push him through the wall in to the basement to save a second, I have yet to recreate it, but apparently it does work.

-I imagine everyone knows about the helicopter cutscene skip as it was in the 3:44 run.

-In the first Buck temple, you can skip the first water rising cutscene by activating the door required to access the second, you can then skip the second water rising cutscene by blowing up the supports and leaving before they explode, furthermore you can skip grabbing the piece of the compass by using a sprint syringe and jumping on to the wall shimmy section, then jumping past it to the end of the section.

-In the second Buck mission, you can skip the cutscene with the large metal thing falling down (When everything's burning) By just jumping on a rock to the right of the cutscene trigger, it's very, very easy and I have no idea why I didn't find it for 7 months

-Ink Boss's health carries between phases. He also takes damage any time he's hit, meaning that right before the final hit, when he does a large recoil before spitting more ink at you, you can kill him before he even recoils.

-You can get out of bounds at a lot of places in Vaas' compound, there are two spots you can jump inside of it early at, as well as being able to access the back, fenced off area, and in the first room of his compound (The first shack) By jumping up beside the stairs you can get over the wall there. Doesn't seem to be useful.

-You can sprint in both of Vaas' cutscene-fights with proper timing.

-There are a lot of small breaks in the cenote;
You can jump down to the first walkway after distracting the first guard, rather than walking around
You can distract the second guard and jump across the gap in the walkway, rather than wait for him to move and slowly follow him
You can slip in to the water in a little gap off the walkway past the waterfall, but the ladder off the boat isn't extended so you can't climb up there. You can however climb up some rocks beside the boat, then climb on to the boat, but nothing up there works. Climbing up on to the docks counts as entering the water, so that will also fail you instantly.
You can just jump to the last checkpoint that places you on the dock, rather than going the whole way around.

-You can sprint in the final walkway of the game where everything is on fire and save about 20 seconds.

I've never been here or posted here before, but I might as well share my knowledge of the game for anyone who cares now or later, I've spent thousands of hours playing this game and I suppose I hold the RTA WR for it as well.

-Getting in front of Grant in the intro sequence makes him move faster, there's another glitch in this game I call prop surfing where you stand on the edge of a prop, it moves, and you ride it along as it continuously accelerates. In the second rock throwing tutorial, if you pass grant, then throw the rock, you could theoretically ride a crate to the end of the area and save a couple seconds (But that would also have a high risk of softlocking the game)

-In the intro area, you can get out of bounds in two spots as has been posted in this thread, but if you go out of bounds at the second spot (During the chase scene) and climb west over the mountain, then look out you can see a small far away island, that island is actually the interior of the cave underneath Dr. Earnheardt's house, by swimming to the back of it in an intersect between blue and green water, you get teleported underneath Dr. Earnheardt's house. From there, you're basically stuck underground, but if you can maneuver around enough to find a blue plant, you can harvest it and you will be pulled above ground, once you're up there you can go to Hoyt's island uninhibited. As anyone that has played this game will know, it is most likely useless.

-If you activate a radio tower just as you run out of range to activate it, or activate a radio tower and take a medical syringe at the exact same time, the radio tower will break and Jason will no longer be able to fall, allowing him to walk on air in a way similar to ISG from Ocarina of Time/Majora's Mask. Probably not useful.

-In the map tutorial with Dennis, the time required for the map to be possible to close isn't dependent on his dialogue, it's actually dependent on the time that passes after you select the Boar icon, if you select it immediately, you can skip 2 lines or about 10 seconds of dialogue.

-If you reduce your health to adrenaline level as you enter the crafting tutorial cutscene, you can use a medical syringe as soon as you make it, pulling you out of the crafting tutorial and immediately starting the Tautau tutorial, skips 30 seconds of dialogue.

-If you switch your weapon at the same time the "Outpost freed" cutscene thing plays, you can move freely during the cutscene.

-If a corpse is moving as you harvest it, and moves away from you, you can skip the harvesting animation, this doesn't apply to above ground plants, instead it just breaks those. It does however apply to underwater plants with you moving.

-In the underwater cave section at Dr. E's, instead of jumping off the cliff in to the water, you can simply jump off the cliff and land on the lower ledge, skipping the whole water section.

-In the section of the cave where you get high, once you enter the greenhouse if you get prop boosted (By the bottle on the floor for instance) and continuously mash sprint, as soon as you gain the ability to sprint you will do so at extreme speeds, this can be used to skip the bats that appear in the next section.

-In Pirate's Cove if the alarm is never activated, there are two pirates in the front area of the cave, and 3 in the back, if the alarm is activated normally there are 5 in the front area, and 6 in the back. However, if the alarm is activated just as you enter the mouth of the cave, all of the pirates in the front area will despawn, and only two will remain in the second area, which you can just jump over and ignore entirely.

-You can skip all of the checkpoints in the burning hotel and go straight to the last one and still have the sequence work properly, unfortunately I have not found a way to skip them without the use of a trainer.

-A guy named Stonehewer found a way to use the sliding door inside of Willis' house to push him through the wall in to the basement to save a second, I have yet to recreate it, but apparently it does work.

-I imagine everyone knows about the helicopter cutscene skip as it was in the 3:44 run.

-In the first Buck temple, you can skip the first water rising cutscene by activating the door required to access the second, you can then skip the second water rising cutscene by blowing up the supports and leaving before they explode, furthermore you can skip grabbing the piece of the compass by using a sprint syringe and jumping on to the wall shimmy section, then jumping past it to the end of the section.

-In the second Buck mission, you can skip the cutscene with the large metal thing falling down (When everything's burning) By just jumping on a rock to the right of the cutscene trigger, it's very, very easy and I have no idea why I didn't find it for 7 months

-Ink Boss's health carries between phases. He also takes damage any time he's hit, meaning that right before the final hit, when he does a large recoil before spitting more ink at you, you can kill him before he even recoils.

-You can get out of bounds at a lot of places in Vaas' compound, there are two spots you can jump inside of it early at, as well as being able to access the back, fenced off area, and in the first room of his compound (The first shack) By jumping up beside the stairs you can get over the wall there. Doesn't seem to be useful.

-You can sprint in both of Vaas' cutscene-fights with proper timing.

-There are a lot of small breaks in the cenote;
You can jump down to the first walkway after distracting the first guard, rather than walking around
You can distract the second guard and jump across the gap in the walkway, rather than wait for him to move and slowly follow him
You can slip in to the water in a little gap off the walkway past the waterfall, but the ladder off the boat isn't extended so you can't climb up there. You can however climb up some rocks beside the boat, then climb on to the boat, but nothing up there works. Climbing up on to the docks counts as entering the water, so that will also fail you instantly.
You can just jump to the last checkpoint that places you on the dock, rather than going the whole way around.

-You can sprint in the final walkway of the game where everything is on fire and save about 20 seconds.
