About This Game

HEAVY METAL. HEAVIER MAYHEM.

Wake up on a mysterious, war-torn island as a cyborg commando and blast your way through an army of absurd enemies. Heavy Mental is a fast, over-the-top co-op action roguelite: every run throws new enemies, new powers and new bosses at you - and a yellow chick with a stick of dynamite is always ready to help.

TEAM UP IN CO-OP

Play solo or grab a friend in online co-op. Cover each other, share the chaos and take down the island's defenders together. Choose from a crew of wild heroes - the Cyborg, the Afro soldier, a samurai, a mecha-schoolboy and more - each with a special ability of their own.

RIDE ANYTHING THAT MOVES

• Walker mechs: shoot the pilot out, jump in and stomp through enemy lines.
• Tanks & trailers: drive a battle tank and hook up weaponized trailers.
• Chases & descents: escape through the jungle in a Cadillac and survive a wild motorcycle ride down the mountain.

AN ARSENAL OF BAD IDEAS

• Harpoon gun: yank enemies toward you and finish them with a spinning kick.
• Dice power: throw the dice and let fate decide - fire frenzy, lightning or pure chaos.
• Super weapons: laser guns, flamethrowers and a satellite beam that burns everything from orbit.
• Turrets & mines: deploy machine-gun turrets and upgrade them right on the battlefield.

GIANT BOSSES

Face mecha-tanks, spider tanks, a four-legged war machine, a monstrous frog, a flying sumo titan, a grenade-throwing general - and a certain grandma who really doesn't want you on her island.

ROGUELITE PROGRESSION

Every run is different. Level up and pick perk cards, spend your gold at the Arcade Man shop, rescue captured rebels to fight by your side and hunt for hidden treasures. Die, learn, upgrade - and go again.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Heavy Mental is made by a small team, and we use generative AI tools as assistants during development (pre-generated content only - no AI content is generated while you play). AI 3D tools (Meshy AI and Hunyuan 3D) were used to create base meshes and textures for some characters, vehicles, weapons and props; every one of these assets was then cleaned up, re-topologized, rigged, animated and styled by hand in Blender and Unity to match the game's art direction. AI image tools (Google Flow / Nano Banana) were used for concept art, UI icons and parts of the store and marketing artwork (such as capsule images), always composed from and edited around our own in-game character models. Gameplay, level design, code, balancing and all final decisions are made by our team.

Mature Content Description

The developers describe the content like this:

Heavy Mental features fast-paced, stylized combat involving various weapons, explosions, and high-octane action. The game contains comedic and cartoonish depictions of violence against an absurd variety of enemies, including cyborg soldiers and armed elderly characters. There is no realistic gore, blood, or intense graphic violence. The tone is humorous and arcade-like, focusing on over-the-top destruction and chaotic fun.
