Clone of BattleZone by Atari. Works best in full screen. Yes, I know BattleZone was first person, but I decided that would be too hard so I just made it top-down. No enemies yet, but that will hopefully change soon. Arrows to move, and a, s, and d bring up settings Volume, Shot type, and graphics quality, respectively.
Credits to Atari for BattleZone, I played it once and it was so fun.
