About the game

Onset is an open-world sandbox built around Lua scripting, with no set objectives to follow. Players choose among a large set of Lua-based commands - hundreds in total, cataloged in the developer wiki - to build their own scripts and game modes. That structure makes it a reasonable entry point for anyone just starting to learn programming. Blue Mountains both developed and published the game, which has been in early access since 2019.

Offers that are not a key (Gift) — show (2) Gift: the game arrives as a Steam gift and works only in the region it was bought for.

These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.

How much does Onset cost?

Is Steam an official store or a keyshop?

Steam is an official store — keys come directly from the publisher or an authorized distributor.

Are keys from these stores legal?

Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

Which key region should I pick?

Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.

What is an activation platform?

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.

What's the difference between editions?

Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
