Inspired by classic video games, Boss Monster challenges you to become a villain, build a dungeon, lure in adventurers, and destroy them! Boss Monster is a standalone card game that challenges 2-4 players to become video-game-style villains and build deadly side-scrolling dungeons. Players compete to see who can attract and destroy the most adventurers. But beware! You must make your dungeon as deadly as it is attractive, or the puny adventurers might kill you first!
