Alien Combat is a top-down arcade shooter. You have to shoot aliens with your tank as they fly down from the sky.
The gameplay in Alien Combat is so simplistic that there isn't really anything else to experience in the game. Controlling a tank, you move left and right and fire repeatedly to kill as many aliens as you can before you yourself get destroyed.
Alien Combat does not offer any variety, just the same gameplay repeatedly. Graphics are very basic, and without any different enemies the game does get repetitive. The only option is to change the difficulty of the game.
Even though Alien Combat is a free game, it is really only made for quick play.
