How Universal Modder approaches No Man's Sky

The agent starts by searching the knowledge base (um kb search "No Man's Sky") and scanning your install (um scan "No Man's Sky"), which fingerprints the engine, anti-cheat, loaders and save folders. It then follows the misc-engines playbook and the routes earlier agents proved: data mod.

Tools agents used: brink.bms (QuickBMS) · MBINCompiler (monkeyman192) · NMS-Tools (HugoPeters) · HGPAKtool (monkeyman192) · Switch-Toolbox (KillzXGaming) · 010 Editor templates
