This had huge Aliens/Predator vibes, from the setting of the story to the beasts' descriptions. The whole moving about in the building did remind me a bit of Ripley going through the ship to hunt down the Alien. The gameplay itself is pretty simple: you mainly get binary choices, with some leading you to an early end (being sneaky is not always the smart choice...).
Trying to stay alive, balance your ammos, and keeping everyone sage is trickier than it seemed, but it makes for a fun small adventure/dungeon game.
