Half-Life 2 Cheats
How to use these cheats
Button names refer to the Xbox controller — A, B, X, Y, the LB/RB bumpers, LT/RT triggers and the D-pad. Unless told otherwise, enter codes from the pause or options menu, or while playing. Some cheats disable achievements for that save — keep a separate save before you start.
- Cheat codes3
Enter the following codes during gameplay on the original Xbox version of Half-Life 2. The White and Black buttons on the Xbox pad sit where LB and RB are on the 360 controller.
