Resident Evil 6 pre-order bonus maps detailed

Check out the Mercenaries mode maps you can score by putting your Resident Evil 6 pre-order in through specific retailers.

As detailed on Capcom Unity, Amazon, best Buy and Gamestop all carry different maps as pre-order bonuses.

• The Catacombs - Gamestop
  There are more than just enemies lurking in these catacombs. Be weary of booby traps ready to ensnare you around every corner! Are your reflexes quick enough to avoid them?
• High Seas Fortress - Amazon.com
  An expansive stage that takes you from the deck of an aircraft carrier to the hangars inside. Engage in intense shoot-outs on the deck, but hone your martial arts skills inside the narrow confines of the hangers.
• Rail Yard - Best Buy
  A multi-level stage in the steel and concrete confines of a railroad yard. Enemies are lurking everywhere, from inside the trains to the roof of the yard. You'll have to stay on the move to stay alive.

Presumably these maps will be available for purchases as DLC once Resident Evil 6 launches in October, for PlayStation 3 and Xbox 360. Mercenaries Mode is a co-operative horde-style multiplayer mode.
