NetHackers is an open challenge to build the first program to win NetHack 3.6.6, a 37-year-old game requiring descent through procedurally generated levels and escape under permadeath conditions. No autonomous program has ever achieved ascension on the modern version, though recent reinforcement learning agents have doubled previous progression records. The project invites researchers to use hand-coding, AI agents, and iterative improvement to tackle this unsolved frontier in AI generalization.
