Keep the Heroes Out!

This cooperative board game has players each taking control of one group of dungeon denizens (all of whom are cute) as they try to do what the title says: keep the heroes out! Especially from the treasure room, because if they loot the treasure, the game is lost! This is a campaign style game, so the dungeon tiles are arranged based on the scenario you are attempting (20 provided). 

On your turn you have five cards in front of you from your own deck which you can then use to command your things around. Move, attack or action which means use the room's special action like get a gold coin from the treasury or use your group's special power. The mercenary gnolls can attack more, the imps can just pull traps out of their butts, the singular dragon can regenerate HP and the ratkins can spawn more ratkins as an example.

After that, you pull hero cards which determines who spawns where. Each hero type has one special power that only applies when they first appear, afterwards they all behave the same which keeps it simple. Rogues disarm a trap where they spawn. Warriors destroy resources. Archers shoot towards the treasure room. Wizards wake up people in the prison. What? Prison!? Yes, on your turn you can "push your luck" and draw three more cards for the low cost of putting a "tired" hero in prison. Unless you pull a wizard in which case, they all wake up!

Managing tired heroes is all part of the game. After the special spawn move any active hero will first try "wake up" all tired heroes who then all get to do stuff! This will be try kill a monster on their tile or try open a chest on their tile. If they do any of those they get "tired" and are basically dormant until another hero (or special effect) wakes them up. Active heroes with nothing to do all advance to the next tile leading towards the treasure room and repeat this process.This can cause a hero cascade if you have too many dotted around the place which is dangerous. At the same time, the only way to win is to go through the ENTIRE hero deck 2-3 times (depending on your difficulty level).   

It's a pretty fun game, though you might only have a few turns depending on the player count and not all the monsters are equal, both in complexity and usefulness.
