Description: Swarm Fortress combines horde-survival and tower defense. You control a commander who must survive waves of enemies. Besides shooting the enemies yourself, your buildings will also shoot, block or generate resources for you. The gameplay is split in two phases: the day during which no enemies appear and you can spend as much as you want placing buildings, and the night during which you cannot build and must survive the enemy waves. Between the waves you will receive rewards such as resources, building unlocks, commander upgrades and allied units.
