About Project Castaway
Project Castaway is survival crafting title set in the vast expanse of the Pacific Ocean. Hunt, gather, fell trees and embark on expeditions to traverse the ocean - discovering desert islands laden with unique resources.
Embark on the life of a true castaway - stranded on a deserted island, with just yourself for company. Scavenge or hunt for food, traverse from island to island and be carefully construct rafts & shelters for when the night comes - it can get awfully cold on these islands...
Being stranded has some upsides, at least. Explore beautiful Pacific landscapes. Swim through shimmering blue water to stand upon golden sands as waves crash against your feet. When the weather turns, take cover under palm trees as the rain pelts the ocean - and listen to the thunder crash overhead.
Use the natural materials surrounding you to construct a base - the key to your survival. Hunt animals, fell trees and scavenge ruined ships as you build your way to safety.
You best keep your wits about you - it can get lonely on these islands, and castaways have been known to lose their minds... Keep on top of your sanity and ensure that you're sleeping well - lest unnatural apparitions appear before you, seeking to take your life.
How much does Project Castaway for PC cost right now?
Project Castaway for PC starts at €4.19 (€4.38 with fees) at Difmark, 74% under the €16.89 (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 €16.89 (no fees) at Steam.
That €4.19 (€4.38 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Just 10 stores stock it, 11 offers in all, so there is little here to push the price either way.

Is it worth buying the Steam Key for Project Castaway now or waiting?
That €16.89 (no fees) key is at its usual price: no bargain, no spike.
- Those €16.89 (no fees) are 8% above what it usually costs, measured on the store price.
- Only 2 stores sell the Steam Key, and with that little competition the price barely moves.
- Not counting today, 300 days out of the 445 days on record were this cheap or cheaper; the lowest it has ever cost is €5.91.
Worked out from 667 daily records of the Steam Key for Project Castaway across 3 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.
Which Project Castaway format should you buy?
With the shared account at Difmark 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 €12.70 (€12.51 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.
The 7 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate Project Castaway in US?
10 of the 11 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive Project Castaway offer?
One listing is worth ignoring: the Steam gift that Difmark Digital Keys has at €22.17 (€23.17 with fees) is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €16.89 (no fees) at Steam.
