This game has so many different things you can do (not only the fighting aspect of the game is interesting but also the crafting and the defece), it deserves more badges
it's very very easy when you realise that the only thing you have to do is build tier 3 units on palisade to win every lvl....and it gets boring pretty fast
This game is very easy first try: 805 kills, the fact that they come in enourmous packs makes it easier just load up the hand gun that fires the blue beams that shoots trough all of them they drop enourmous amounts of bonuses which will constantly freeze them and speed you up
