will feature "Mercenaries Mode." That's the good news. The bad news is that Capcom is spreading three additional maps for the mode across three separate retailers as pre-order bonuses.
Gamestop pre-order customers will receive The Catacombs map, Amazon purchasers will obtain the High Seas Fortress and Best Buy buyers will be granted the Rail Yard. Capcom has some teaser images of each on its Unity
If you aren't looking to spend $180 to obtain all three merc maps, we're sure Capcom will make them available as DLC for a nominal fee sometime after launch.
