^ know that,when i was playing Total Overdose,and there was a mission,you were detached from a train but you got to cathcup with the guy who detached it and kill him,and when u get close to the train he activates an anti aircraft gun and shoots the bike.You have an SMG(which is the poorest weapon) and you're supposed to destroy it so u can get on the train.It's health was nearly at the end,and i hit a rock and flew off the bike.
Lol.
