How does region lock work?

Does it block you based on IP location? Eg if I am on vacation in Asia will I be able to play?

yeah they said it blocks you based on IP. If you’re not in a supported region, you unfortunately won’t be able to play

is this for eu or us? that they have confirmed

sb else asked a similar question as OP. They did not specify, so I’d assume both

Im in Korea traveling right now and had to use vpn to download the game. My steam is from am allowed region but still had to use it, hopefully won’t have to use it to play and at max, just use it to start the game.
