About The Tartarus Key

The last thing Alex Young remembers is being at home alone in her apartment… so why has she suddenly woken up in this strange mansion? All the doors are locked by bizarre puzzles and traps, there are cameras following her every move, and she keeps thinking she sees… things… out of the corner of her eye. If she wants to escape alive, along with the other captives she discovers, she’ll need to use her wits in this adventure thriller.

Inspired by the look and feel of classic horror games, The Tartarus Key serves up a mystery filled with twists and turns, and more than a few deadly surprises. Rely on brains over brawn to help Alex survive, but beware - not everyone might make it out alive.

Features:


  • Escape a deadly mansion filled with dangerous traps, and rescue Alex’s fellow captives… or fail, and leave them to a grisly fate
  • Uncover three different endings, and dig to the heart of the mansion and the strange secrets it and your captors hold
  • Solve puzzles and challenges reminiscent of escape-the-room games in a variety of unsettling and bizarre scenarios
  • A tense, atmospheric adventure that relies on puzzles and plot instead of combat or chase sequences

played though this puzzle mansion and while the game is fine i do think all the added text slows the pace quite a bit stopped opening the optional dialogue just to get through it when i got the game initially i did expect it to be more of a resident evil style puzzle game (from the 3rd person cutscenes) but it's actually just a fairly simple first person puzzle room style game with chill music the puzzles were actually pretty good, but i just didn't enjoy the game, and ended up tuning out when others had to be saved

8/10 spooky puzzle game. Most of the puzzles are decent and simple, one or two left me clueless. Not difficult to 100%

A great "mansion full of puzzles" game with some really inventive puzzles. Undermined somewhat by the fact that you get a disappointing and nonsensical "bad ending" for failing a misleading puzzle early in the game which gives you one try, while all of the other puzzles give you unlimited tries. And the only way to change it is to play the whole game over again. (Or save scum, which I would've done if I'd realized that that one early-game puzzle would decide which ending I got.) Still, the puzzles are good enough that this is a recommend overall!

Really enjoyed it. I like that the rooms have their own puzzle and you don't have to leave it to solve it. Though admittedly, I over analyzed some pretty simple puzzles.

A very entertaining escape room mix of Resident Evil, Zero Time Escape and Saw. The dialogue's a little...much and tends to interrupt the immaculate vibes, but other than that, this is a great puzzle game with real consequences for wrong answers. Highly recommended!
