Evil purple enemies of the SYSTEM have invaded it and you are the only security bot, who is able to defend it. Shoot at the enemies to delete them, along the way collect upgrades as fast as you can or you are good as dead without them! Survival of the fittest even in the harsh world of the SYSTEM.

The infernos, in different size, shape and colours, are there mocking and sneering at you. All you have got is a SnowMan, who has some snow balls. Shoot the infernos with the snow balls to freeze them. Freeze them, get points. But it is not an easy task. As you go up, you will come across many obstacles; your snow balls may be teleported, they may not be big enough to freeze a large inferno, etc. So play safe, don't get burned!

Prepare for big Attack. Place your tower more eficiently and kill all dangerous monsters.
