Kernel Hearts Punch angels, dethrone God

Punch angels with up to four friends

You and up to three co-op friends climb the Tower of Babel as members of the M.A.H.O.U Unit, cutting through angelic creatures floor by floor. Each level ends in a boss fight against that domain's guardian, so runs have a clear rhythm: loot, fight, survive, boss.

Combat is fast hack-and-slash. You mix attacks, spells, and movement powers picked up during the run to build combos, dodge finishers, and clear packs before the pressure builds. Early runs feel spongy and short, then it clicks once you unlock more chips, relics, and characters. Bring co-op friends who like learning systems together.

Chips, transformations, and tower friends

Between expeditions you return to a laboratory backup on the edge of humanity's last holdout. There you spend run rewards to unlock and equip up to 256KB of chips onto your MAHOU.OS, tuning each unit to your taste.

In the tower you can draw on its strength to dispel the Heavenly Curse, hitting nearby foes hard and taking your true form for a short time. You also meet the tower's inhabitants and give them gifts to deepen bonds, which opens more upgrades and encounters. The look is colorful anime against an ash-drowned world, with strong music carrying both fights and quiet moments.

What should co-op friends know before climbing?

How does co-op actually work?

You team up with up to four players total to climb the tower together, sharing the same loop of clearing angels, grabbing upgrades, and fighting each floor's guardian. It suits a regular group that can die, retool chips at the lab, and go again.

Can you play it solo?

Yes. The same structure holds alone: explore a floor, mix attacks and spells, beat the guardian, return to the lab to equip chips and give gifts to deepen bonds. Solo runs demand more learning, since no friend can cover you while you figure out combos and timing.

Why is the start so hard?

Starting stats are thin, enemies scale fast, and a timer keeps pushing you forward, so farming everything is not an option. Prioritize chests, souls, relics, and bond goals over killing every angel, then spend rewards on chips and unlocks. The second character and a fuller chip board change the feel a lot.
