Your mission in this shooter is to test a new Supertank. Unfortunately, testing it involves dropping you behind enemy lines and seeing how far you can make it before you get blown up. Luckily, your overlords are not without compassion, and they are willing to give you health upgrades and better firepower as you rack up kills of your own. WASD Keys- To move around, Mouse- To aim and shoot. Space-bar- To fire missiles (when you get them). For the upgrade menu, just move your cursor to the edge of the screen.
