That whole backwards jumping thing is a load of bullshit. You don't go any damn faster. That sounds more like a way to validate a cheat.

The game multiplies your velocity by 120% when you jump, but doesn't allow forward velocity to pass 120%. If you are backwards, and crouching, the game doesn't properly turn 'backwards' speed into 'forwards' speed, so it keeps multiplying your speed as you keep jumping. And since there's no friction if you bunnyhop perfectly... you can go ridiculously fast. The fastest place you'll really see it though is approaching glados, there's no other hallway big enough.

Holy crap! I need to learn some of those tricks!

Quality post, flechette - and I did notice a speed-up from the bunnyhopping at about 2:05. I'm not shocked an engine with roots in the Quake series still has a few physics tricks left to exploit.

I did the whole "running backwards" thing before I called bullshit. It didn't work. At all.

Then you're doing it wrong. Jump forward, turn around in mid-air, crouch, and jump right when you land, and continue jumping. It's not easy to do. It's not just ... turning around and jumping backwards.

Nope, just tried it, and it didn't work. I didn't get a speed boost - just fell down and hurt myself on the fire mantel.

NEWBS, if you can't strafe jump then you can't do this either
BTW I'd seriously doubt that this is viable on the 360 version... takes a mouse to do this kind of tom-foolery properly

God this makes me want this game even more. Looks like somebody's gonna go buy the Orange Box next week when he gets paid.

that's pretty incredible. i've played some of those levels plenty of times and never thought of some of that stuff.

Personal Favorite was the companion cube level, ignoring all of the powerballs.
