Final Fortress

Defend the Nuclear Plant against soldiers, tanks, helicopters and various other attacking enemies. The enemies come in waves and you are armed with a very powerful Cannon to keep them from destroying the nuclear plant. You will earn cash that will help in repairing and buying upgrades at the end of each level. You can also buy mines to place in the paths of incoming attackers. After the first few levels, you need to have a real strategy to succeed, simply trying to shoot everyone will no longer work.
