A destructible-world physics game where every pixel of rock, water and lava is live matter, and you have all the powers of the earth. Play a volcano professor turned superhero across a story campaign, or open the sandbox and do whatever you like to a living city.
MOLTYN is a superhero physics sandbox. Laser, gravity, water, lava, storm, freeze and a nuke are each a real force acting on a fully simulated world: melt it, flood it, freeze the sea and throw it. The free demo has five story missions, taking you from a harbour rescue to a city-sized kaiju, a fight against a copy of yourself, a meteor storm and a job on the Moon; each ends on a report card that leads with how much of the city is still standing. It also has two sandbox worlds, The Island and Blank Canvas, with the sandbox editor: spawn any NPC, object, vehicle or material, then switch straight back to superhero mode and play with what you built. Early Access will have the first 10 of 18 planned story missions, plus six sandbox worlds.
If you'd like access and haven't received a key yet, email andrew@moltyn.io. The free demo is also public on Steam from 6 October 2026.
MOLTYN is made by Hingston Digital Pty Ltd: one developer, Andrew, in Griffith NSW, Australia. It reached 10,000 wishlists off the back of Indie Game Joe (@indiegamejoe) sharing the first trailer. Thanks, Joe! MOLTYN clips have since drawn millions of views across social media. The Steam playtest drew about 3,500 testers, the majority of whom rated the game 8 or higher out of 10 for fun, and MOLTYN now sits at about 21,000 wishlists.
