I played it on Xbox and then again with the extra chapters on Orange Box for Xbox 360. The other day I was looking for it again on Xbox One because the Orange Box is backward compatible. Unfortuneately I don't have my hard copy of the game anymore. I'll either borrow my friend's copy or buy it again digitally. Great game. Car controls were a bit wacko, but otherwise super great. Oh, I remember now. Last time I played I used the Grav Gun through the whole game for an achievement. It was surprisingly useful and fun in place of a projectile weapon. You still needed the rockets for a few enemies however.
