Zero G JumpĪ tiny little hole in the zero gravity area of Chapter 9 allows runners to take the effect from zero gravity for the rest of the level, even in areas out of bounds.
Using nothing but a table and an elevator, runners can skip a huge chunk of chapter 10 - the biggest single skip in the run. This can be used in strategic places to skip fights or elevators. Because of that, the game still sticks you to surfaces and tilts the game world around you as if you were still in zero g, tilting Isaac. This physics-defying trick is done by transitioning out of a zero g zone while meleeing, which makes the game think you’re still in zero g. The boost can be affected by Isaac’s starting animation, as well as the frame in that animation, framerate, angle, among other things, it’s certainly no easy trick. Making Isaac actually do the boost is the easy thing, but getting him where he needs to be is a whole other thing. Of course, even with the inputs being made a lot easier, that doesn’t make the trick easy at all. Then all they need to do is hold the spacebar and aim into the wall, buffering the alternate fire so it triggers the first frame you aim every time with ease.
Runners make the setup for this trick much easier by unbinding “stomp,” which otherwise would interfere with the boost. If you aim into a wall and on the same frame perform the alternate fire of the Pulse Rifle, the game will shoot you away with a massive amount of speed. The Pulse Rifle has an alternate firing mode where Isaac crouches down and fires the rifle 360 degrees around him. So that’s step one of the trick, for step two we’ll need the trick's namesake, the Pulse Rifle. This was likely implemented during development to prevent you from shooting at or interacting with things on the other side of the wall - which funnily enough you can still do with some ingenuity. You can see this yourself by simply walking up to a wall and aiming, the game will push you away slightly. In Dead Space, weapons collide with the game world. Pulse Boosting was found September 2020 by r3sus, the contributor to many different strats for Dead Space 1 and Dead Space 2. Pulse Boosting is a trick that abuses the Pulse Rifles alternate fire mode which allows the main character, Isaac, to go flying, skipping large portions of the game. With the help of Looney, let’s dive into the tech that broke Dead Space wide open: Pulse Boosting.
The Dead Space series strikes fear and adrenaline into the hearts of its players, and with rumors of a reboot to the series as well as Dead Space premiering at Summer Games Done Quick - now is a very special time for Dead Space speedrunners.ĭead Space is a little over an hour of brutally challenging tricks and skips, coming together to form an incredibly difficult (and satisfying) run.
