Subnautica 2 for free — let your PC foot the bill
Subnautica 2 is out on Steam and it costs $29.99. Your PC sits idle for hours every single day — put those hours to work. The app runs AI jobs on your graphics card, the balance climbs while you sleep, and about ten days later you are diving Proteus without having spent a cent of your own.
- What Subnautica 2 costs: $29.99
- What you pay out of pocket: nothing
- What an RTX 4090 needs: about ten days
Three steps. That is the whole thing.
No catch, no subscription, no small print. You rent out your graphics card for AI compute and get paid for it — during the hours you were not using the machine anyway.
Switch it on, forget it
Install the app, hit EARN, get on with your day. Setup takes about a minute.
The card works, the balance grows
Not gaming? Your GPU runs AI jobs. Launching a game? It steps aside instantly. You get paid by the hour.
Collect Subnautica 2
Swap the balance for Steam gift cards, top up your wallet and buy the game like any other.
How many days does your card need?
The target is small — 29.99 GUSD, the price of the game. At eight idle hours a day an RTX 5090 gets there in about eight days, an RTX 4090 in ten, and an older RTX 3090 in roughly three and a half weeks. Pick your exact model in the calculator and see your own number.

You pay with Steam credit
Your balance turns into Steam gift cards, the cards top up your Steam wallet, and the wallet buys Subnautica 2 at the same $29.99 checkout everybody else uses. The catalog stocks Steam cards in $50, €20 and €10 denominations, so you can cover the game and keep the change for the next one.
Redeem the code on Steam, the funds land in your wallet, you buy the game like anybody else. The original Subnautica is in the same store, if you would rather start at the beginning of the story.

Frequently asked questions
You build a balance with GamerHash AI, swap it for Steam gift cards and top up your Steam wallet with them. You then buy the game the normal way — except your graphics card covered the cost, running AI jobs during hours the machine was idle anyway.
Your card is idle anyway. Point it at Proteus.
Setup takes a minute. After that you simply leave the machine on, and about a week and a half later your Steam wallet holds more than the game costs.
