A friend of mine here at 38 Studios just launched an iPhone/iPod touch game. It’s called Keep Defenders, and is described on the site as: “Keep Defenders is a highly addictive, fast paced real-time combat game. The object of Keep Defenders is to defend your keep as waves of enemy soldiers attack from all directions. If your keep is destroyed or you lose all of your units, you have been defeated. Use your spoils to hire reinforcements and turn back your attackers!” It’s pretty darn fun, so give it a go! Check out the video after the jump.
