Wow, they must have shown a lot of cut material in those videos they released on their YT channel, I barely recognized any maps. Anyway, ABH is gone, Wallclimbing is gone, and every glitch involving the Portal gun. Can’t wait for Ep3 \>\_\> Ah well, who’s ready to start looking for new bugs? 😛 ---

Bhopping classic is back. Strafe jumping is back. Crouch jumping is gone. Wall strafing is back. Portal bumping is still here. I haven’t test any of the other oob glitches yet. GET HYPE! ---

Oh wow, I got this weird fucking speed boost randomly today, I was talking to Igge about it earlier, I thought I knew what caused it, but I’m still not sure, all I know was that I was holding down A. I’m going to keep looking into this. I’m not even trolling, I’m being completely serious. ---

You can get L4D2 style boosts from jumping on slopes (Or does it work on other Source games too?) EDIT: [http://www.youtube.com/watch?v=CMaeX7j13io](http://www.youtube.com/watch?v=CMaeX7j13io) Jump to 1:55 ---

> You can get L4D2 style boosts from jumping on slopes (Or does it work on other Source games too?) Yeah that’s never been gone. So far it’s been more of a hindrance to me. I can’t space my jumps as well because every time I try and use it, it’s always been down a staircase and I’ve face planted some crazy wall they’ve put there.

Haha, the top comment on that video is already “you are gonna make portal 2 speed run soon?” ---
