Keep The Heroes Out - Boss Battles expansion - Part 2: Unlocked cards & Monsters

Unboxing the Dungeon Defense Co-op game: Keep The Heroes Out: Boss Battles
Face off against other Monsters as Bosses (while still defending against Heroes). If you're lucky, turn them to your side as playable characters.

The minion monsters (bats, puppies, skeletons, and slime) can all be played as their monster as well as them being controlled by their overlord (vampire, werewolf, reaper, and king slime). In fact, it's generally a very good idea as you get far more use of the minions when controlled on their own as well as being able to take orders from their overlord.
