Can somebody please explain the new dr. skip where you keep the storage to skip the explosive wall and skip the predator room. Struggling alot on it particularly the last glide to the second oob.

It's called Medical Skip. If you post a video of you attempting it I can probably tell you what you're doing wrong, but the glide is fairly simple. Just jump off the ledge, turn slightly to the left, wait half a second, then turn all the way down (on keyboard, on controller the turn down is a bit more precise).

I've been getting it pretty consistently recently. All I was doing wrong was not going down because the camera view looks the same when gliding in a straight line when you're gliding down.
