What kind of height do you get out of a Horde Jump?

If it's significant you might be able to skip going inside the building right before The Crane on Dead Air. If you wait just a bit in the fenced area instead of jumping over to the other side and heading up the fire escape you'll usually (always?) face a horde. With enough height maybe you could jump up to the open window of the building you're supposed to enter or the rooftop of the crane building itself.

I haven't tried the Horde Jump myself as I'm playing on a 360 and without a cheat mode it seems like a waste of time.

Also, is anybody able to check the sides of the buildings in that area to see if there are any viable places to jump to? It looked like a fairly straight forward set of jumps could get you from the fire escape to the window ledges that basically lead straight to the crane rooftop but I fell through the only one I tried to jump to.

Edit: If a straight up Horde Jump like that were enough to get you to the window/roof I'm not sure if that would prevent the potential Tank encounter in the building but if you DO run into that Tank (and it might be worth reloading until you get one in a segmented run) you could probably coax it onto the roof of the crane building without much trouble. From there you could lead it up on top of the roof access room (the building/room straight in front of you when you come onto the crane roof). It would probably be a "simple" matter of getting a Tank Boost to the next roof over which would bypass the Crane Jump entirely (if the Tank cooperated and boosted you in a timely manner).

It appears to be entirely possible and probably fairly easy but it remains to be seen how quickly it can be pulled off. Setup time may be prohibitively long.

Edit 2: Well, the setup time for a Tank Boost would have to be rather quick indeed. If you do the Crane Jump as normal you can just jump corner-to-corner to get from the second building (there are four rooftops, you start out on the first with the crane and jump to the second) to the fourth (the corner that has the broken section next to it) bypassing the third entirely. Doing this I can't imagine engineering a Tank encounter would be worth the effort/damage sustained.

Crane Jump to corner jump seems ideal.

Edit 3: Or assuming you don't have to avoid any killzones you could do what would seem to be two Horde Jumps and bypass the rooftops/buildings entirely. Instead of using the sand pile to jump over the fence to the left to get to the fire escape before the crane building you would Horde Jump the section of fence to the right and just run down the alley between the buildings. You'd need to do another Horde Jump to get over the fenced area at the other end(s).

Normally waiting for a random/natural horde spawn might take too long but there is a car with an alarm within sight of the roof of the third building which a teammate could set off (before jumping to a heroic time-saving death).

Last night while playing the 360 version I was able to get on top of a group of horde however I didn't get a boost and I could only jump off them as if I were jumping off of anything else. That didn't seem to be very helpful for anything though.

Do you take fall damage if you land on top of a zombie? What if they're climbing when you fall on them? There is a pipe leading up to rooftop four that you can jump to easily from rooftop three (avoiding the ledge grab). I'm thinking if you could jump onto a zombie coming up that pipe (or do some crazy zombie ladder jump on your way down) that you could drop down to street level safely from rooftop three and avoid the buildings altogether.

There also seems to be the possibility of a Tank Boost from building three down onto an awning that you would normally exit at if you had gone through the buildings normally.

Also, possible to jump to that light pole from rooftop three? Seems like you might be able to jump to that and then to a ledge on the side of the building to make it to the ground.

fuck you i wont do what you tell me

on Dead Air, level 3, you can jump from the railing to a ledge on the left, over the wood barrier.

can't believe that I didn't find this myself, i tried, but i couldnt make the jump i guess.

^does not care for console's

Most of the skips seem to be avoiding crescendo moments...

Also found that you can move crates and other stuff by shooting it. You could move it to these crescendo and try jumping over them.

No Mercy level 4

at the beginning, you can jump onto the stone gate, then onto the metal part of the gate. from there you can either jump down to the street, skipping going around the right side, or you can jump on the trucks on the left, then continue to the left to save a bunch of time.

don't have a vid, just figured this one out.

You mean Death Toll level 4

Anyway, if we somehow manage to find three other players, I'm definitely willing to be part of a coop run on PC. A split screen video of the run would be lovely, though I don't know what is the SDA staff's opinion on this matter (and more importantly, what is nate's opinion on this matter)

yep, meant death toll. sorry. Tongue

problem with this game is that randomness affects every single aspect, with the exception of the environment. Valve seems to be patching things up, and as such, any run for this game will likely need to be done on the 360 in order to keep a constant version...

and that's a shame, because the PC version would be much more fun to watch (and preform).

Edit: New trick: Blood Harvest level 2

from the start:
go down one floor, turn left into the first room, fall out the big window and press against the wall as you fall. when you hit the ground, you will have taken no damage, and can book it straight to the room ahead.

Quote from MGP:

dont think so... I'm talking about the level with the warehouse at the start, then the trainyard up ahead, with a door that sets off an alarm. that's level 2 iirc. either i hit a ledge on the way down, or I hit garbage bags when i hit the ground, but I think it's the first one, as zoey made a "getting hurt" sound, but didnt actually take any damage.

Doesn't work, I'm taking massive damage out that window. There's no garbage bags, and in between the two windows is a small light about half way down, though I can't angle to the side and stand on it. I just clip right through it.

I'll see if I can replicate it then. I know that I managed to do it though. must've hit something on the way down. took no damage.

Landing on regular infected does not break your fall, but in the nature of landing on something higher than the ground, you will take less damage than if you missed and hit the ground.

Landing on regular infected kills them. This explains the difficulty in preforming large jumps using infected.

Edit:

couldn't replicate it, but found a better trick in the process. see the cart out the window? if you walk out the furthest right window in the room and land on the handle, you only take 6 damage.

I would make a video, but I don't know how to use the demos system in the game.

No Mercy: Stage 2
Generator Room

get on top of the high wood shelf (there is a part of the white tank that sticks out, allowing you to jump up on the tanks, then walk to the shelf).

if you can get a boomer on the low wood shelf, you can jump on him, then up to the ledge, skipping the crescendo moment. it probably works with normal infected as well.

Offices (after generator room)

one of the offices has a window that you can fall out of onto some post boxes. you take no damage, and it allows a straight run to the safe house.

No Mercy: Stage 3:
The Gas Station:

If you get on the closest semi-trailer to the window (you can climb up from the rear), and there is a tank spawned, a well-timed tank boost gets you on to the ledge, skipping the scissor lift crescendo event.

Death Toll: Stage 2:
The Bridge room

Stand by the fallen fence. if there is a tank spawn, bait him behind you (quite easily done by climbing up the ladder), tank boost yourself across the cap to skip the crescendo event.

Death Toll: Stage 3:
when you see the first train with the flatbed (when you have to climb the stairs on the left to jump on the train to go over the fence), a running jump on to the wheel of the flatbed, followed by a second jump will get you on to the red train, with enough luck (its a far jump).

Death Toll: Stage 4:
At the forklift event, a tank boost into the area where the forklift is will boost you up to the ledge and past the event trigger.

Death Toll: Stage 5:
Upon seeing the park sign, there is a path with a railing that heads left, and a large tree beside the start of the railing. if you head to the right, there is a rock ledge that you can jump on to, saving some time in walking.

Dead Air: Stage 2:
-The already known crane skip

Plank Crossing:

-before the offices really begin, you cross a wooden plank to get to another office building. Once you cross this, turn around and look left. you should see a building that lacks any real rooftop.

If you have 92+ health (it knocked me from 100 to 8) walk off out of the window (don't jump. if you do, you die) and hug that building (requires a bit of air maneuvering). You should take heavy damage, but you will make it safely to the ledge low on the building. fall to the ground. Follow the alleyway, and you should come out of the alley that is right by the car alarm, with the next safe house on your left and across the street.

-only worked in buddha mode, strangely enough. after i turned buddha off, it dealt 100 damage and i died.

Dead Air: Level 3
Airport Entrance:
-just as you exit the doors, turn left. there is an airplane turbine with a fire in front of it. the high ground is in the fire, so run through and jump on. move to the left side of the turbine, and jump up. You should stick in that area. jump again, and you will be on top of the airplane. walk down and turn left into the parking lot.

Dead Air: Level 4
Main Terminal Crescendo:
-once you start the van, hug it's right hand side. as it breaks through, run, run, as fast as you can. throw a pipe bomb back, get into the luggage area, and if you get far enough, the crescendo is nullified, and hardly any zombies follow you.

Blood Harvest: Level 2
One floor down from the start:
-walk out the right window, aim for the handle of the cart. will take about 7 damage.

After triggering the Crescendo:
-run as soon as you open the door. go up the stairs, out the first window. hug the wall, there's a ledge. drop on to the train car, then to the ground. book it to the safe house.

Blood Harvest: Level 3
The Bridge:
-climb up on to the house. This is done by going around back to an object with a rounded roof. there are nubs at the bottom that can be climbed on to, then you can jump on to the roof of the object, then on to the roof of the building. From here, a tank boost gets you on to the cliff, from where it is an easy walk to the safe house.

Blood Harvest: Level 4
The Train Station:
-upon seeing the station (the house after the fall), go as far along the cliff as possible (do not fall down to the station). There is a gas trailer there. jump to it and walk along, and it will provide you a bit of cover until the next cabin.

The House:
Press up against the train car. If there is a tank, and you time the boost right, you should be able to get on top of the car, and be able to make it to the safe house easily before the tank catches up.

Nice finds.

To record a demo you need to open the console and type: record <insert demo name here>.
After you have finished recording type into the console: stoprecord
To play it back type into the console: playdemo <insert demo name here>.

Hope that helps you record ^^

The demo files are mixed in with a bunch of other files so just look for the ones that have .dem on the end.

If your in the games console type in demoui2. A UI will appear which allows you to load the demo (which opens right to the correct folder), change speed, pause, play, etc.

fuck you i wont do what you tell me

alright, thanks.

Yeah, I've determined that jumping on enemies hurts them, and thus, throwing things on them must as well (using sb_stop, which is basically stopping all AI).

This is why you aren't allowed to stand on any of the special infected for any length of time. you have to jump quick. If you jump on a witch, you basically get stuck until she claws you to death, and the others have you floating around on top, so that you don't actually touch them.

Now, for future testing...

Pipe bombs do not move you with explosions.

HOWEVER.

Pipe bombs move objects that you can stand on (carts, garbage cans, etc).

Therefore.

Unless objects in midair are unjumpable (which may be the case), it may be possible to lay a pipe bomb under a garbage can, jump on the garbage can, and use the garbage can to jump after the initial explosion. However, the explosion causes objects go go flying all sorts of different ways, making it highly unpredictable.

Quote from Neverdown:

in the game, there are points where the team is blocked by an obstacle (say, they have to go up a lift, or break down a wall). They have to activate something in order to get past the obstacle. And for some reason, removal of said obstacle always creates a ton of noise, and as a result, hordes of zombies come rushing in. This usually sets the team back about 2-5 minutes, and if the team isn't co-ordinated enough, they will be hurt by the hordes as well. The skips I found are very situational, but considering how we would be rolling for the best random set up we can find, that's not really a problem.

Movie of No Mercy 3 here
Demo for the movie here

I've been messing around making demos of myself beating levels on expert just with the bots and No Mercy 3 (Sewers) is the easiest level so far. Just run all the way through the level. I get to the lift way before the bots and they get stuck in the open and all the zombies go to them and I literally run to the end of the level. Everything after that is empty. The only specials you may run into are tanks/witches but you can just run past them. I did it in about two minutes.

I have no idea if it would work online if three people sacrificed themselves. Would that even be allowed? Could they type /kill if needed? Well, all I know is that when the panic music is playing if you just run ahead the levels tend to be empty, like only so much can be going on at once.

When you watch my little demonstration also check out the tank juke. You guys know how to not get killed by a rock, right? He cheats and throws the rock where you're going. So you should start running to the side as he warms up then after he throws stop and run the other way and the rock should miss.

There were actually a lot more zombies in the sewer than usual. Most of the time there's just 2-3 scattered about.

Also, panic > crescendo.

Questions:

Tank boost what? On expert a tank attacking you = one hit incap. Or am I missing something?

Is there a way to prove a run was done on expert if the player doesn't take damage? Perhaps using a hex editor or something.

Did someone mention a trick which allows you to teleport the bots to your current location? Or am I on crack? I did a search for bot, teleport, warp, AI and didn't find anything but I swear someone said that. That would be of tremendous help.

The bot teleport seems to happen somewhat randomly, and only if you're a certain distance away from them. Turn off clipping and fly around, they should randomly pop to your location every now and then. And /kill should be ok, as you dont need sv_cheats on to do it. And with 4 people, you should be able to pass any hard part by only sacrificing one person at a time. And theres probably a command that shows relevant information on screen the whole time like difficulty and maybe play time, though i dont know what it is.

Ah, I see, too bad. I thought there was a specific trick. When I was doing No Mercy 3 sometimes the bots would live instead of getting massacred and I'd be chilling in the safe room at the end while the bots were doing bot things on the other side of the level. I know what you mean though, sometimes 1-2 teleport up to you but it seems there may be a range limit.

It would also help a lot on finales for positioning because bots are absurdly clueless.

who ever said anything about doing this on expert? Tongue

tanks hit you a long, long way horizontally, but give very little vertical distance (if you get lucky, you could probably get 3-4 metres out of it).

I'm sure that you could do a vertical tank boost if you could fall on his arms just as he swings, but I don't see any real use for it, with the exception of the turbine room in No Mercy 2.

I haven't played the game much (only demo) so just ignore me if I'm wrong. Since the game uses Source, would it be possible to use a pipe bomb etc item to fly like in HL2? This would have probably been posted already if it worked, but it's worth a shot.
