Hardfought

Hardfought is a nethack community with its own servers, similar to NAO. Hardfought currently hosts three servers in Vermont, London, and Sydney.

Hardfought has its own IRC channel on freenode, #hardfought. This is also linked with the #nethack-hardfought channel on the Roguelikes discord. The Beholder bot announces important events, deaths, and ascensions, and Pinobot can be used to find information on enemies across NetHack variants.
