Super Mario Bros. X2

About

Super Mario Bros. X2 is a fan-made platformer that expands on the SMBX fangame by letting players design custom levels and episodes. Use built-in tools to build worlds with over 500 new objects and enemies or join others in co-op and competitive modes. The game supports split-screen multiplayer and includes a battle royale-style mode for chaotic head-to-head action. Scripting via LunaLua adds deeper customization for advanced creators. Released in 2015, the game thrives on community contributions. Forums host thousands of user-made levels, keeping the content fresh years after launch. It runs on PC, Mac, and Linux with no online requirements. While not officially licensed, it captures the spirit of classic Mario with modern tools. Best for players who enjoy building as much as playing.

Storyline

Super Mario Bros. X2 is a mod and expansion of Redigit's SMBX fangame in which players can create their own Super Mario levels and episodes! The mod adds hundreds of new assets and features for level and episode construction. It also adds LunaLua, a branch of the Lua programming language, which allows players to create just about anything. If level and episode development isn't your thing, check out the official SMBX forums for levels and episodes aplenty!
