Brogue

Brogue is a free roguelike computer video game created by Brian Walker. As in its predecessor Rogue, the goal of Brogue is for the player (represented by the character @) to descend to the 26th floor of the Dungeons of Doom, retrieve the Amulet of Yendor, and return to the surface. Players also have the option of delving deeper into the dungeon to obtain a higher score. This task is complicated by the presence of monsters and traps in a procedurally generated dungeon.
