Kernel Hearts is a unique blend of action RPG and roguelike elements with multiplayer co-op. As part of the M.A.H.O.U Unit, you are tasked with climbing the Tower of Babel, eliminating the angelic creatures in your path as you dethrone God and save a world drowning in ashes.
Mix and match your attacks, spells, and movement with unique powers during each run to unleash devastating combos on the enemies you encounter. Punch biblical monsters in the face with up to four friends. Each level culminates in an intense boss fight against the domain's guardian
After each expedition, you will return to the last memory backup in a laboratory located on the outskirts of humanity's last holdout. Spend the rewards from each run to unlock and equip up to 256KB of chips onto your Unit MAHOU.OS, and customize them as you see fit.
Harness the strength of the tower to dispel the Heavenly Curse from yourself, unleashing a devastating attack on nearby foes and attaining your true form for a short period.
Interact with the tower's unique inhabitants and give them gifts to deepen your bond.

Hey everyone! Akira, Kernel Hearts director here. It's been almost a month since the game came out, and today we're happy to release our first content patch! We dug into your feedback to identify some of the most requested features and improvements. We still have work to do, but I'm happy we could get this out ahead of our original estimate of late October. This means that almost everything on the October Roadmap is now out, except for the English voiceover! Here are some of the changes: Training Mode We've added a training mode that's accessible right after finishing the tutorial. Here, you'll be able to experiment with any Mementos, Relics, and enemies you've come across during your expeditions. There's also a very fun vertical movement challenge. What a thrill. {STEAM_CLAN_IMAGE}/45227059/ff27a6f35477b53baa38046d9c205d550378d2c0.png {STEAM_CLAN_IMAGE}/45227059/90202836bc0d4c41d3db3...

Read full update on Steam ↗Hey everyone, Akira here, Game Director of Kernel Hearts. Today, I'm very happy to announce that Kernel Hearts will be launching one month from now, on September 17th! To celebrate, we decided to update the Demo one last time before release. Japanese Voice Acting Japanese VO has been added to the game! Make sure to start a New Game to enjoy all the story scenes with the new Japanese voice acting. Attending these recording sessions was a dream come true for me. Watching the actors bring these characters to life was incredibly fun, and easily one of the highlights of this year. Balance We've listened to a lot of your feedback, and as a result we've done some pretty significant rebalancing across both the game's combat and economy. For combat, we've adjusted most Mementos and Relics so they scale better with player level, while also rebalancing them to make every choice feel more rewardi...
