Project X Zone is a crossover tactical role-playing game for the Nintendo 3DS. The game is a follow up to the video game Namco × Capcom and features characters from Namco Bandai, Capcom, and Sega. Stages in Project X Zone take place in grid-based locations from the game's many crossover titles. Each friendly unit is made up of two characters (thus referred to as a Pair Unit), though a third character (or "Solo Unit") can be added for once-per-battle assistance. Unlike Namco × Capcom, units can move freely within their range on the field map, with no penalty for accessing treasure chests or destructible objects prior to attacking.
