Grand Slam Secret Level [Ion Fury]
One of the most ridiculously difficult secrets to solve in recent memory, the retro FPS Ion Fury includes a secret level that can only be accessed by inputting a code through a piano. Just getting the proper notes requires you to track down more secret rooms, find the notes, then combine them into a secret code — so if you’re not familiar with piano sheet music, this is a tough one.
Secret Monastery Room [Fire Emblem: Three Houses]
There’s nothing better than discovering a secret that’s been sitting under your nose the entire time. Throughout the lengthy Fire Emblem: Three Houses campaign, you spend most of your time at a monastery-turned-academy where officers are trained in the arts of war.
After finishing the story and starting a new game, you’ll be able to unlock a hidden chamber below with a map of the world and other useful goodies — like a powerful spell. It adds a new function to the world too; an amiibo scanner! If you have any Fire Emblem amiibos, that’s where you can finally use them.
