In multi-
player games, having other
people assist you in getting leaderboard position or achievements (xbox 360 specific) by having other people help you in ways that go counter to the game'
s design. Most often done with one team throwing the game to another.
Example: In Battlefield:Modern Combat, one Achievement acquired by hitting
5 enemies and 0 friendlies in one mortar strike. This is doable but, during normal play, exceptionally hard. Boosting would be getting 5 people you know to join the other team and all stand in one place so you could
drop a mortar strike and get the achievement.
