Half-Life 2: The Orange Box Cheats :
Glitch - FALL OUT OF TEST CHAMBER 4
by Unregistered Feb 04, 2009
in order to do this glitch, you must activate both infinite health and portal placement anywhere cheats. infinite health cheat code is LB d-pad up RB d-pad up LB LB d-pad up RB RB d-pad up. portals anywhere code is YABABYYA d-pad left d-pad right. alright, first, fire a BLUE portal at the first camera (the closest one to the entrance) and when the orange portal opens up, you should fall out of that chamber. i havn't tried this on any other test chamber so i think it only works on chamber 4. have fun :-)
Code - Portal Cheats
Unverified. I do not know when these cheats are entered, try during gameplay and paused! The Rocket Projectile code may not function, and it looks like the Portalgun ID codes allow more than 1 set of portals. Also, I do not know what the Upgrade Portalgun code does when you have not yet grabbed the Portalgun. These codes were from the Steam GCF if anyone is curious.
