Horrible game.

This gets old quick. You play until a new alien appears, then you lose and go buy upgrades. Then you START FROM THE BEGINNING and play through until a harder alien appears and you lose and have to do it all over again. There's no strategy involved; you just keep doing the same thing over and over until you eventually win.

4 groups of 4 mobs first one is yellow with no skill second is blue with healing ability third is red with more health and fourth is faster. first group: normal ground walking aliens. the only type that walk on ground. second group: flying. third: flying and look like a caterpiller (yay more space to hit) fourth and last: a spaceship, about same size as third group a bit slower i thing but can't be pushed with lazers from under. (it didn't reach my bouncers so i don't know if they do anything do it) 

the most annoying part about this shallow game is how it start and ends they just show you a 4 frame picture of how we accidently killed some aliens which sent war signal to them and the end is @spoiler@ humans bragging about the victory and calling you a newborn hero @spoiler end@ would NOT recommand to anyone with the slight sign of intellect.

there isn't much to say more about this game except don't be afraid to hack it. it's not worth playing with or without hacks it's just a crappy game with not enough action.
