A downloadable mod

Custom Throne is no longer updated, get Nuclear Throne Together instead!

Custom Throne is a modding toolset that lets you make your own Nuclear Throne levels, weapons, characters, enemies, areas, projectiles and mutations. It runs on a modified version of Update 19 of Nuclear Throne.

Changelogs can now be found here.

If it asks you for version 4.5.2 of Microsoft's .NET Framework, you can get it here: https://www.microsoft.com/en-us/download/details.aspx?id=42642
