Apartment 666 is a short monster-hunting game set in a single location, the titular apartment. You play the game over a course of 5 Acts. The set up, the monster challenges, and then the conclusion.
Depending on whether or not you have 2 victories or 2 phobias, you either succeed the ordeal or your greatest fear has come for you.
From what I can tell, the game seems stacked in the monster's favor. You need to roll 1d20 and if your role is higher than the monster's HP then you win, and most monsters have a number higher than 10. This might be by design, but there's not really an indication either way in the rules.
I played as someone who thought they were a competent monster hunter, only to find out that they have absolutely no idea what they are doing and ended up trapped in the house forever. You can read my playthough HERE
