You are in an alien base and have to pass through all the rooms. Kill all the enemies in order to pass each room. Each enemy has a color which can be only destroyed by a Laser-Bullet of the same color.
Monsters must protect San Francisco or even the world from these evil aliens. Place your monsters around the map to defeat the incoming waves of aliens.
You escaped the orbital space station and survived the explosion. Dr Rycroft left co-ordinates and now you need to investigate what experiments he performed on you. Beware though, he has surrounded himself with hi-tech defenses.
Load your rifle and shoot the flying skeets. Different colors of skeets represent different scores. Reach the goal by hitting the target and you will make it to the next level. Just don't shoot the pigeons. Good luck!
