great. i finished it. only minutes after my last comment. demons are unlocked now. i don't know, kings guard were very tough, but this time, they nearly sent none of those units! it's all about luck?
I have found a way to survive Extreme situations in the Defense Mode. Run around while placing barrels. The barrels explode immediately (because of the previous one's explosion) and kill any enemy that comes near. If you don't get stuck, this is an ultimate way to gather weapons, kill lots of zombies and stay alive. In the little pauses you get, build up your defenses.
please make it possible to delete guns in paused modus, or add a "delete all guns" button. i'm at 1200 again but everything is so slowed down i can't even delete guns properly to end the game and cash in the highscore.
