Unreal Tournament III

Self explanatory. This is awarded after you have completed a match on every mode in Instant Action. For the fastest time with this just set every match type to lowest requirements with the Speed Freak mutator on. You can even turn off bots in the TDM and Warfare modes, so you are then just completing the objective to win the game. The trophy will pop after you finish the game in the last mode you had to play.
