The Earth has once again been invaded by a horde of aliens, and it's up to you (as an isolated resistance fighter with an itchy trigger finger) to stop 'em all by your lonesome. The future of the planet is in your hands, can you finish the job...? The Earth is under attack by vicious aliens that are intent on annihilating the planetuand all its inhabitants! There's only one man with the strength and courage to stand up to this threat and save the world from total destruction: Jon Steadman. You take the role of Steadman as you face off against some of the meanest and most cunning alien foes you've ever encountered. You're a one-man army up against alien maniacs, bikers, robots, and giant roaches. Luckily, you have a huge arsenal of weapons at your disposal, so you can launch cluster bombs, sonic blasts, and nuclear smart bombs on the aliens and watch them fry! While you'll have your hands full with the army of aliens, your primary objective is to disarm the Doomsday Bomb and rescue the human hostages. If you don't think you can handle it by yourself, team up with a friend and take on the enemy together.
