Normal Tanks is a single-player overhead shooter with plenty of heavily armored combat vehicles, turrets and mechanical creatures to shoot at. There are only four playable levels included in this demo version, but no time limit to restrict you from replaying the game at higher difficulty settings.

Weapons can be upgraded by collecting red stars, and you can switch between the two weapons at any time by pressing the right mouse button. It wouldn't be surprising to hear that some players would even attempt to input the Konami code during the title screen, considering how much the overall theme, level designs, and boss encounters resemble the original Contra game.
