We have to deduct points for the lackluster online gameplay, which left us wanting to go back to Modern Warfare 2 and score a few more kills. Multiplayer includes all the planetary minigames (Quarian Sharking, Prothean Sudoku, Smear the Hanar, and Volus Bowling), a split-screen "catch-the-collector" mode, and online head-to-head battles or 4v4. Online co-op has been removed from the game, which is a shame, because it worked so well in Mass Effect 1.
