what a nice game ^^ not too long or short :P you get to know the diffrent Towers, and in my case.. not know how it feels when your defences get breached and the zombies run to the goal :P
i will say the ligth mashinegun, with the rigth upgrades, can melt most of the waves away with ease ^^ you just need to put your two pals up with some anti armor guns and you are set for a nice and easy game :P
hmm i like this game, but well at medium the npc's mostly stand arund to be sniped easely, i guiss it improves on the hard or insane mode. tho.. killing last boss with a score of 20 kills and 2 deaths feels a bit emty :(
i do hate how i fooled my self to think i should all the way over to the red X, and had to get the schoolbus after 2 level XS "how the meow can i get all the way over there in´only the bus?"
