Halo: Combat Devolved is a fan-made demake of Halo: Combat Evolved that reimagines the game as an 8-bit, Game Boy Color-style action title. The game adapts elements from the original Halo into a top-down perspective, featuring simplified visuals and gameplay inspired by classic handheld games. Early builds include the levels Pillar of Autumn and Halo, along with recognizable weapons and enemies from the original release.
