## Key points

- Commercial PC, web and mobile releases become free from 2027.
- Console exports will still require an Enterprise licence.
- GameMaker has powered Undertale, Hotline Miami and Spelunky.

## Summary

YoYo Games will let developers commercially publish games made with the latest GameMaker tools on PC, web and mobile without paying for a Professional licence from 1 January 2027. The change lowers the cost of releasing games made with the engine, which has been used for well-known independent titles including Undertale, Hotline Miami and Spelunky.

GameMaker, a roughly 26-year-old toolset focused mainly on 2D games, has been free for non-commercial PC use since 2023. Console exports will still require an Enterprise licence and approval as a developer, with existing tier pricing unchanged. Current Professional licence holders can continue selling games made with the existing GMS2 runtime and will also gain access to its source code.
