The idea is to let the players play the monsters while the Dungeon Master plays the heroes.
First, I set up a basic dungeon by placing some doors and furniture and prepared one stack of monsters for each player.
Their goal was to prevent the heroes from stealing the treasure chests.
I then sent the Dwarf in the Arena. He fought bravely but had to run away when he had only one body point left after a fierce fight against a Fimir.
This time it is a victory for the Monsters...
The game was really fun for the kids but I guess I couldn't play it too often since they asked to play the heroes again right after this game.
Nevertheless, a complete new way of playing Heroquest is emerging from this game. Next time I could also let the players place some traps where they want to or give them several objectives so that they do not concentrate all their figures at the same place...
In conclusion it was a nice and funny experiment...
