Your mission in this cool shooting game is to blast enemies and upgrade your warrior as you try to save the planet from impending doom. You were sent to the past to change the course of events. Use the WASD KEYS to move around and use YOUR MOUSE to aim and fire. Fight through each level and upgrade your arsenal. Don't forget to upgrade your own defenses or you may soon find yourself in a lead-ridden heap on the floor. Use the right weapon for the job, aim for the exploding capsules and for your own sake. Good luck!
