Elden Ring Bosses in GTA V (called Elden Los Santos in game) imports Elden Ring boss models, rigs and animation clips into GTA V story mode and gives them GTA-side encounter behaviour. Malenia, Starscourge Radahn, the Fire Giant (enlarged to about 60 metres for helicopter fights) and Godfrey each get their own contact timing, stagger and defeat, and you fight them with GTA’s guns, explosives, cars and the Buzzard. The source release adds travelling fireballs, Radahn throwing traffic, police and SWAT support, custom second phases and filming cameras. Bosses can fight each other.
It’s a mod plus a local asset-conversion toolkit: you supply GTA V Legacy and Elden Ring, and the tools build a private asset package. It ran on an M3 Ultra through CrossOver; the README says the newest additions haven’t been checked in rendered gameplay. The v0.1.0 source release went up on 6 October 2026. The repository has an AGENTS.md but doesn’t say whether an AI agent wrote the code, so it’s marked unverified.
