Jagged Alliance 2: Unfinished Business is a turn-based strategy game in which you command a squad of mercenaries defending the newly-independent nation of Arulco from a predatory corporation. This is an expansion to the game Jagged Alliance 2, and you can import your character from the original game, but you don't need a copy of Jagged Alliance 2 to play this. If you've played either earlier Jagged Alliance game, you'll be familiar with the basic system mechanics; there are few changes here. The only really new thing is the addition of a scenario editor.
