GB: "Red Faction: Armageddon has a completely different system when it comes to the mechanics of the game from Red Faction: Guerrilla, everything is generally the same but things seems to flow a lot better when it comes to the controls. The biggest change from the last game though is that developer Volition took out the multiplayer/versus and replaced it with a co-op mode the is pretty much wave after wave of enemies to annihilate with up to 4 of your friends, which is a lot of fun I must add. Taking out versus in a game though in no small change. There is obviously the campaign and RUIN Mode which I believe, you can only play if you purchase the game new. In RUIN mode, it is literally destroy as much as possible within the time limit and it is a blast."
