Dungeon Prospector is old-school dungeon crawler/roguelike. You're in infinity dungeons (in length and width) full of monsters and treasures. How far can you go and how long can you survive?
It's early days for this game, but Dungeon Prospector is one of the few first-person "free-look" Dungeon Crawlers in the style of King's Field or Ultima Underworld. There's not a lot to do just yet, but it is tremendously pleasing to see such a game being developed. Updates look promising, let's hope this game continues to grow!
