UnNetHackPlus was a variant of UnNetHack 4.0.0, maintained by Bulwersator. The main intent of the fork was to put more randomness, challenges and fun into UnNetHack. UnNetHackPlus incorporates many changes from other variants and patchs as well as its own to form into a fun and balanced variant.
Development on UnNetHackPlus ended in 2013. Some of its features were incorporated into later versions of UnNetHack.
