An expansion in the Dungeon Twister series of games. As all expansion, it can be played as a stand-alone game (if you know the rules from the basic game, available on the game website and you have a set of card). You can also combine it with the basic game and other expansions in order to have a different set of team and room each time you play.
This particular expansion is focused on giving characters muscles. Most of them move slower than typical characters, but they are among the very strongest and most diverse characters in their combat abilities.
