Hi there, while our last two uploads had very simple gameplay, this game is something else. This game is typically an easy to learn hard to master one.
Aliens are invading our earth and you have to defend an important nuclear factory. Do this by buying cannons and tell them what to do. You also need to make strategic decision about what cannons you buy and what upgrades you make.
After 10 levels you have beated the Newgrounds version of the game.
Play this game with the mouse only and don´t forget to have fun!
