About This Game

GnollHack transforms NetHack, one of the greatest and deepest games of all time, into a modern roguelike experience. Animated graphics, immersive sound, music, voiceovers, and a refined interface bring the classic NetHack formula to life. With extensive gameplay and accessibility improvements, GnollHack is a great way to start playing NetHack today!

The Legend Returns

For decades, NetHack has defined depth and complexity in gaming. GnollHack takes that foundation and improves it with modern design, accessibility, and immersion, without sacrificing what made the original great.

Endless Possibilities

Every run is unique. Procedurally generated dungeons, unpredictable encounters, and countless items ensure that no two adventures are ever the same. Win with strategy, creativity, and clever thinking, not with reflexes.

Designed for Modern Players

Clear visuals. Rich audio. Whether you're on a quick session or a deep dive, GnollHack fits perfectly into how you play today.

Depth That No Other Game Matches

Complex systems. Meaningful choices. Real consequences. GnollHack offers a level of depth and emergent gameplay that few modern games even attempt.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

GnollHack features 'Overseer', an optional in-game AI assistant. Using external generative AI models, Overseer provides live-generated text responses to players during gameplay. Players can ask questions about mechanics or request contextual hints based on their current game state. AI content is strictly limited to text chat, and the service utilizes safety filters and prompt guardrails to ensure responses are safe, relevant, and free of illegal or harmful content.
