Play The Battle of Olympus Online

So The Battle of Olympus is this NES game where you play as Orpheus—except instead of being the sad musician from the myths, he's a full-on warrior trying to rescue his girlfriend Helene from Hades. (Yeah, they took some liberties with the story.) You'll wander through ancient Greece smashing cyclopes and minotaurs with your sword, picking up better gear along the way, and begging the gods for help when things get rough.

It plays a lot like Zelda II or Faxanadu—side-scrolling combat, maze-like areas, towns where you can restock—but without the leveling system. The real challenge is tracking down three hidden love fragments before Hades' underworld even lets you in. Some of the enemy designs are great (pegasus fights feel appropriately epic), though good luck figuring out where to go next without a guide—those maze sections don't mess around.
