"Major Alien breakout from Security. Stun and re-capture before mutation."

You are Chief Security Officer on the planet 'Koventri' where all the captured space invaders are kept until a humane way of dealing with them can be found.

There has been a major breakout and it is a race for time to stun the invaders and carry them back to the security compound. After being in the open too long, they mutate and become much fiercer.

See how long you can keep them all locked up! The object is to stun the aliens with your laser, catch them before they hit the ground, and carry them back to the security compound.

Good luck!
