So it seems the title has asked a nice question of you dear friends.
CoDhead? Haloid? Star Craftian? Share your voice, and respect others whilst doing so.
Because the satisfaction and sheer badassery of taking on multiple zombies at once while spinning around is great. I refer to of course, the Living Dead playlist of Halo:Reach.
None. I don't play multiplayer, unless it's an MMO, and then I just play it as if it's a single player game anyway.
