10 Hidden Video Game Items That Change EVERYTHING

10. The Zeta-Pi-Omega File - Hades

After Hades' son, Zagreus, grows tired of being confined in the underworld, he vows to flee to the surface. But since the underworld was designed to be inescapable, Hades throws everything he has to ensure his ungrateful son stays put.

While you attempt to break out of Hades' hellish maze over and over, you'll encounter many characters from Ancient Greek myths such as Achilles, Thanatos, and Zeus. However, the people that most players are drawn to is Orpheus and Eurydice. Although these two musicians adore each other, they're imprisoned in different sections of the underworld, preventing them from rekindling their relationship.

Or so it seems. If you keep speaking to the pair upon each run, your step-mother, Nyx, will tell you that you can release Orpheus from servitude by locating the zeta-pi-omega file in the administrative chamber. Once this order is sent to the Contractor, you can purchase it, buying Orpheus out of his sentence.

When you revisit Eurydice upon freeing her husband, you'll see she and Orpheus have been reunited, and are celebrating with a heavenly duet. Even though this ordeal has no effect on the main campaign, it's a beautiful moment, knowing your actions brought these star-crossed lovers back together.
