The Z-Slide technique. Pronounced "Zed-Slide"

It's called the Z slide because normally Jason slides along the X-axis which is basically going to the left/right. The Z axis is where Jason slides towards the in-game camera or the background, each kind have their own use.

For the early foam Z-slide: Start up with an odd angle which is done by standing on a slope and look up, then move the stick to the 11 o'clock position and you can go forwards by moving the stick to the 1 o'clock position, every time you sprint and then crouch to perform a crouch slide, the angle adjusts making it possible to go around some obstacles.

Early missile Z-Slide: Run then Crouch to Slide. During the slide, move your left stick to the 11 o'clock position. Then to move foward, rotate slightly to the right to the 1 o'clock position and then repeat two more times (2nd slide to adjust angle again, 3rd slide to go around the obstacle).

100% use: At the moment, I do know a place where a Z-slide is useful, just before the intended missile weapon room, there is a medium size missile blast plate, you can Z-slide around that obstacle skipping having to go through the ceiling -> crawl space.

Idk what changed but I got this first time now xD I just couldn't get the angle to stick for some reason...

Thanks though! Maybe add this to resources?
