ElimiNation - gamefront.com

ElimiNation is a classic turn based wargame entirely controlled by mouse and featuring an easy to learn interface, a deep gameplay and great replayability. Campaign will let you challenge your skills at Elimination by playing three of five campaign maps each. You’ll control Dark Brigade, Green Wings and Tech Empire. Each faction has some unique units, and those maps have special victory conditions (some are by turn number, by conquering a region, and so on) and also special events (reinforcements, resources bonus, etc).
