Falcon's Eye is a version of the roguelike video game NetHack which introduces isometric graphics and mouse control.

[3] Falcon's Eye has been praised for improving NetHack's visuals and audio to an almost commercial level[3] and has been noted by Linux Journal as among the best free games available.

[3] The objects and enemies in the game are no longer represented by minimalistic ASCII characters, but now have actual graphical representations.

Whilst adding some features, such as a path finding tool, Falcon's Eye doesn't alter the NetHack gameplay.

[3] Falcon's Eye was developed by Jaakko Peltonen, a researcher of neural networks at Helsinki University of Technology, originally as a separate engine, and then grafted onto NetHack.

Peltonen explains that this versatility helped him to create Falcon's Eye, as he did not have to work around a fixed character-based interface.
