Boss Monster 2 is quite a lot of fun though it takes a few games to find out why certain cards matter and until then can appear more shallow than it is. The game is quite fast so not all the mechanics are revealed immediately.
Players place down up to five room cards in front of their boss monster to lure and defeat heroes that turn up in the central “village”. If the heroes are defeated by accumulating damage through the sequential rooms then the player gains soul points, but if they survive and face the boss monster then they are taken as wounds.
