Breach 3 is a squad-level tactical combat game in a futuristic sci-fi setting. Aliens and robots are some of the enemies you face in battles witnessed from a top-down perspective (contrasted with X-Com's isometric viewpoint). Your squad leader gains experience from each completed mission - assuming he doesn't die, ending your campaign prematurely. Combat is real-time, but pauses automatically when you need to make important decisions.
An added feature of Breach 3 is that the program can link up with Impressions' game Rules of Engagement 2; character attributes and experience can be transferred between the two games.
