In DICE's Battlefront II, most campaign levels are unique, with little resemblance to the maps available in multiplayer in terms of structure. In Pandemic Studios' and Rebellion Developments' series, campaign levels often utilize maps made for multiplayer as a base. Maps can also refer to levels in campaigns or other special modes. On the other hand, large modes in DICE's series like Galactic Assault or Capital Supremacy, which have maximum player counts of 40, use very large maps that are often sequentially fought in with the use of phases.
In DICE's series, small modes, such as Cargo or Strike, which consist of less than 20 players, often use maps with lots of close-quarter areas and are relatively small. Maps are often designed for the game modes in which they are playable.
