Single player refers to a game with only one human participant; in contrast to multiplayer.
In this mode it is possible to play:
- where the computer AI (Artificial Intelligence) follows a basic strategy and all factions start from scratch (unless prebuilt units is on).
- which are a series of battles that follow a scripted story line and assign you certain targets (build unit x, take island y, destroy specified target) in order to progress. Battles may start with a (large) number of units already built and the battlefield will expand as the game progresses.
