A really easy way to win the game is to go on the undead, buy the halberd person with your 500$ then in a game put autospawn and keep it in 1 place i beat the demons on first try
this isnt a guide, and for your information they are undead halberd are really weak BECAUSE they are slow. If the enemy charges at you with a few axemen you waste your money, or they send clusters of bowman or archers and you get overrunned because they require less time to make and they'll do enough damage to make your lines falter.
