Demon Stalkers

100 levels, 2473 ghosts, 586 scrolls - and one wicked demon

Blast bad mages, mutant rats, and murderous monsters. Explore mysterious multi-level mazes. Annihilate hordes of ghosts, snappers, and dervishes to claim magical artifacts and treasure. The action won't stop until you get to the bottom of it all - and hand Calvrak the Demon a one-way ticket to oblivion.

• The deeper you go, the harder it gets. (You might want to bring along a friend to help.) But don't wait 'til you find a Slow Death curse to use the Save Game command.
• Scrolls give you hints, magic, and the saga of the Marble Vaults. If you'd rather, write some history of your own.
• Use the Dungeon Construction Set to design your own worst nightmare... and then inflict it on your friends. With over 200 design options, Demon Stalkers' horrors can be as infinite as your imagination.
