i have completed the 4th level of defenders it looks ok. 
this level of the game centers around you attempting to stop robots coming from yes aliens (i change who is killing you every time :) ) from destroying your tower witch if you can defend will take back this land for the forest. The defender i am playing as here is the brute defenders who is great at combat but loses a lot of health while fighting. it makes him easy to get into playing but hard to win the final level with. you can also play as the wizard who can dish out pain but can't take it. anyway hope everyone enjoys the game when it comes out.
