Red Rogue

Red Rogue is a sidescrolling roguelike-like game made with Actionscript 3. Descend into the Dungeon of Chaos, retrieve the Amulet of Yendor, kill all who stand in your way and return with your prize.

Like magic items in Rogue, all of the runes start off unidentified. You have to cast them to find out what they do or use an identify rune. Unless of course you have the chaos rune, which will always have an unknown identity.
