THE LAST FRONTIER
On a distant planet, your mining operation has come under attack from hordes of alien creatures. It is up to you to defend the fortress from these mindless beings. The aliens come from all directions and it is up to you to make sure your soldiers are at the right place at the right time to defend the walls. After each wave you must recruit new units to strengthen your defenses. Failure is not an option. Use YOUR MOUSE to select units and send them to the required side of the base. Use the WASD or ARROW KEYS to move the camera. You can zoom out and back in using the buttons at the bottom of the screen. Good luck!
