So we know Operation Raccoon City will feature a U.S. Spec Ops team alongside the U.S.S. men and women, though the former is only playable in multiplayer modes. Still, they're a major part of the story, acting as the Umbrella team's rivals during the campaign, so Echo Six earns a spot in today's trailer.
The new Operation Raccoon City trailer introduces the two squads member by member, with the U.S.S. team kicking things off as the game's protagonists. See, at least they get to dress like badass sci-fi super agents. The American squad just looks weird, and they even stuck in a couple characters with African and English accents.
