About DO NOT OPEN
WARNING: This video game may cause seizures in people with photosensitive epilepsy. Caution is advised.DO NOT OPEN is a terrifying short and fast paced first-person escape-room experience, based on randomness in puzzle combinations, and classic survival-horror mechanics.

Mike Goreng is trapped in a warped version of his own home. What's going on? Where are his wife and daughter? As a scientist, Mike can't come up with an explanation for what is happening, but his instinct tells him that he is in severe danger... and something evil lurks in the darkness.
Being in Mike's shoes, you will experience tense moments where your heart rate will accelerate. Meanwhile, the personification of guilt, which Mike feels for betraying his family, will try to trap you.
Will you be able to run away from it?


The story of DO NOT OPEN takes place in the grand Victorian mansion of Mike's aunt Judith Goreng who, after committing suicide, leaves the house to her nephew.
Remember to explore every corner of the mansion and discover all its details.


DO NOT OPEN is a challenging survival-horror classic with gameplay based on escape-room mechanics. Each time the player crosses a door of the Hall of the Victorian mansion Judith's Manor, he will enter a different layer of each area, and its puzzles and riddles combinations will change randomly so that each game is different from start to finish.

To unravel the terrible mystery of the manor, the player will find different newspaper clippings, diary pages or other items in each game, making the plot a puzzle in itself. But he must do it before time runs out, or he'd better hide from the terrible threat that stalks him.

How much does DO NOT OPEN for PC cost right now?
DO NOT OPEN for PC starts at €16.14 (€17.01 with fees) at Key4Games, 31% under the €24.50 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €24.50 (no fees) at Steam.
This is the lowest price it has ever been recorded at.
That €16.14 (€17.01 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.
Only 3 offers across 3 stores carry it, and thin supply means the price barely moves.
Is it worth buying the Steam Key for DO NOT OPEN now or waiting?

- Those €24.50 (no fees) are 7% below what it usually costs, measured on the store price.
- Only 1 stores sell the Steam Key, and with that little competition the price barely moves.

Worked out from 746 daily records of the Steam Key for DO NOT OPEN across 1 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy DO NOT OPEN from?
One caveat worth €0.24 (€0.11 with fees): the €16.14 (€17.01 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €16.38 (€17.12 with fees) — €0.24 (€0.11 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.
Which DO NOT OPEN format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Steam costs €8.36 (€7.49 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Can you activate DO NOT OPEN in US?
All 3 offers are Global, so the code redeems on any account no matter where it was created.

WHAT YOU SHOULD KNOW BEFORE BUYING DO NOT OPEN STEAM KEY?
