Super Mario Bros. X2

The Modern Evolution of SMBX

SMBX2 is the definitive modern continuation of Redigit’s legendary Super Mario Bros. X.
Unlike the original, which was abandoned in 2011, SMBX2 is an open-source overhaul that adds the
LunaLua scripting layer to the engine. This allows creators to program new mechanics,
bosses, and cutscenes that were previously impossible, effectively turning SMBX from a simple level editor
into a powerful game creation tool.

Key Features

Massive Roster Expansion: The original five-character roster grows with
Rosalina, Wario, Yoshi, and guest characters such as
Samus Aran, Mega Man, Solid Snake, and Klonoa.
Each has unique movement and gameplay behavior.
LunaLua Scripting: Advanced creators can script custom UI, boss logic, new power-ups,
and fully custom gameplay systems.
Moondust Editor (PGE): Replaces the older editor with a modern workflow that supports
multi-selection, layers, and fast testing.
Backwards Compatibility: SMBX2 is built to support original SMBX 1.3 episodes and preserve
years of community-made content.
