About Subject 13

Subject 13 is the new adventure game developed by Paul Cuisset—the man behind "Flashback", "Future Wars: Adventures in Time" and "Moto Racer"—in partnership with Microïds.

This is a true adventure game. It depicts a mysterious universe filled with secret hiding places and all kinds of mechanisms that the player discovers, analyzes, and activates. There are also objects to collect and to figure out how to use in the backdrops…

Subject 13 will make you travel from a secret base that has been abandoned to a strange and mysterious island, so you can discover the real story. You'll have to muster all your insight and intelligence for this daunting challenge.

Key Features

  • Stunning 3D rendering
  • Intuitive interface
  • Progressive difficulty
  • Quality dubbing

How much does Subject 13 for PC cost right now?

Subject 13 for PC starts at €0.40 (€0.78 with fees) at Kinguin, a Steam key, which is 92% under the €9.99 (no fees) it costs on the official store.

That €0.40 (€0.78 with fees) already includes the SEPGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Just 9 stores stock it, 9 offers in all, so there is little here to push the price either way.

That puts it 12% under its average of €0.50 since 2017, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Subject 13 now or waiting?

That €1.09 (no fees) key has never had a real discount yet.

  • The Steam Key has been on sale for 112 months and its biggest drop has been 6%.
  • Only 5 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, the Steam Key was at this price or lower on 103 days out of the 317 days on record: this is basically what it always costs.
If you are in no rush, it is worth waiting for a sale. We have seen it at €1.04 and we will tell you the day it drops.

Worked out from 759 daily records of the Steam Key for Subject 13 across 9 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.

Can you activate Subject 13 in US?

8 of the 9 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Subject 13 offer?

One listing is worth ignoring: the Steam key that GamersGate has at €9.99 (no fees) is more than 12 times the cheapest offer and is not what this game costs. The number to work from is €0.40 (€0.78 with fees) at Kinguin.
