Dungeon of Despair

1980s style dungeon using fully painted 3d dungeons and lasers terrain and miniatures. What starts as a quest to retrieve a stolen crystal ball turns rapidly into the need to escape the dungeon just to survive.Full of traps and puzzles alongside and encounters to engage with. Originally a training area for an ancient civilisation the dungeon has no doors and appears impossible to navigate completely. However on entry players only receive a limited number of doors that they can place in the walls to access rooms and only have the air they enter with. They must navigate a route out  with limited room access and within the time frame before their air runs out.  I've run this with my current group to check playability. Happy to provide photos if required.
