First map I went to had my daughter. I played again to really enjoy the game, though. Definitely 5/5. Maybe have it so you can store weapons and survivors? That would be really cool.
Bravo! This game was fantastic! It was very fun going through and playing the game multiple times to unlock everything. The Omnistrike for the Barbarian was the most fun thing to use in the game for me. One thing I'd like to see, though, are the masks for the hero providing bonuses related on how to unlock them. For example, the gas mask would make it so gas couldn't kill you.
My "Get The Awards Fast" Method:
Beat level 1 so you have access to level 2. Begin level 2, pick a tower that shoots, and hold shift. Constantly click on one area until you cannot do this anymore. Do this again with Structures, and in no time, you'll receive all of the awards for this game.
