Rogue

In Rogue, players control a character as they explore several levels of a dungeon as they seek the Amulet of Yendor located in the dungeon's lowest level. The player-character must fend off an array of monsters that roam the dungeons. Along the way, they can collect treasures that can help them offensively or defensively. Rogue is turn-based taking place on a square grid, allowing players to have time to determine the best move to survive. (wikipedia.org)
