Halo 3, i'm notorious amongst my friends for taking vehicles were they probly shouldn't go, lol, so that level were you take on the Scarabs with the 4-wheelers, i drive mine to the top of one of those cranes overlooking the battle and gun it right off the end and land on the scarab

Fallout3, first time i used the railroad gun. snuck up on that Pennyworth guy at the top of the hotel, *CHOOO CHOOOO head shot XD

most disapointing, i'd hafta agree 1000 heartless in KH2. i was all ready to hafta redo it at least twice, and i never got below half health. definetly shoulda been a reaction fight with nothing but former boss'
