How much does Under The Island for PC cost right now?

Under The Island for PC starts at €15.29 (€16.86 with fees) at Kinguin, a Steam key.

That €15.29 (€16.86 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 5 offers from 5 stores — and thin supply keeps prices steady rather than falling.

Is it worth buying the Steam Key for Under The Island now or waiting?

That €15.29 (€16.86 with fees) key is at its usual price: no bargain, no spike.

  • Those €15.29 (€16.86 with fees) are 1% above what it usually costs, measured on the store price.

  • Not counting today, 148 days out of the 231 days on record were this cheap or cheaper; the lowest it has ever cost is €11.40.
It is not a bad price, but it is not this Steam Key's floor either. If you are in no rush, we will tell you the day it drops.

Worked out from 570 daily records of the Steam Key for Under The Island across 6 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 Under The Island in US?

All 5 offers are Global, so the code redeems on any account no matter where it was created.

Is Under The Island worth it?

Critics put it at 80 out of 100, though there are only 19 reviews published so far.

Most common FAQs when buying Under The Island for PC in digital format:

It is a key that will allow you to download the game Under The Island on your PC from official download platforms.
As of 23/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Under The Island on PC is €15.29 (€16.86 with fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Under The Island to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Under The Island, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
