Invinco

Invinco is a Space Invaders variant. The player controls a tank at the bottom of the screen, firing towards incoming enemy warriors. Four bunkers can be used to hide from enemy fire, but they will slowly get destroyed. There are different warriors with different behaviors, such as warriors that become invisible for a while, warriors that take more shots and a bonus UFO that flies over. Once a wave is destroyed the UFO will come towards the player.
