If you don't have an Ukraine account.
1. Vpn with Ukraine IP.
2. Setup new account.
3. Add new card. I used Revolut.
4. When adding go to Google maps in Ukraine and select any address and copy it. Or Google Ukraine address generator.
5. Google Ukraine phone generator and copy any of them.
6. You don't need the vpn after that to download.
After reading a few comments I tried to find a way to do this safely.
Extra steps:
1. If you have a main steam account.
1.1 Create a 2nd Windows user to install steam, the vpn and to download the games.
1.2 Download the game(s) I would only advice single-player games.
1.3 Start the game to verify you own a license.
1.4 Select Go offline on steam.
You can be in offline mode indefinitely.
799 is about £18
949 is £21.55 as in the screenshot.
If you HAVE to do this though, as a min. just ensure this is on a fresh account and always play via a VPN. Whether it'll work or not, is your own decision.
Do this at your own risk.
