Namco × Capcom
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.
