[@KoL] Colosseum is double battles. The base games are primarily single battles. Colosseum has you play a renegade who uses explosives to blow up criminal bases after infiltrating them as a member. The base games have you play a kid who incidentally foils the bad guys by stumbling across them. It seems like such a horrible step backwards in both regards. You're thinking of Stadium. Also, is no one going to pay much attention to Henry's flashbang?
