Swarm is a very interesting game of shoot the bad bugs. The idea is to shoot the bug but not to get shoot yourself. you have 4 towers that will take a certain amount of shots and they disappear!!
In Swarm you control a tank equipped with a powerful laser gun. Evil bugs are invading, and it’s up to you to protect your base. Use the LEFT and RIGHT arrow keys to move your tank, and the SPACE BAR to fire your weapon.
Some of the enemies will be different colors, if you shoot one of these enemies a power-up crystal will drop. Collect the crystal for one of seven special effects including a smaller and larger tank, and an extra shield.
