Shoot the enemies down with an arsenal of weapons and get as far as possible
As Always, Good Luck and Have Fun.
Move Left, Right A, D. Use shield-S, Select Weapon 1, 2, 3, 4. Reload-R, Throw Grenade-Space Bar. The objective of the game is to move forward and keep killing the hostiles that want to prevent you from advancing. Upgrade your favourite weapons or health at each checkpoint. This will help you get more firepower and get further in the game. A strategy would be to keep upgrading a particular weapon so it gets souped up. Upgrade your health only when you have low health.
