Mission briefing

In this tower defense game, enemies come from the top of the screen. They move down to invade the earth, which is at the bottom of the screen. The player needs to protect the earth by building defense buildings in the space.

The space is divided into grids. The buildings block the enemy movement and some even fire bullets to kill enemies. These enemies also attack the things that block their way. So, the player needs to survive and kill all units within the time limit before the enemy reaches the earth.
