MOLTYN is a destructible terrain physics sandbox where every pixel is real matter that melts, floods, freezes and falls. You are a volcano born superhero with all the powers of the earth. Dig, flood, erupt and fight walking Kaiju across an 18-mission story, or wreck free-play worlds however you like
Everything is real!
MOLTYN is a destructible-terrain physics game where the whole world is a live simulation.
There is no scenery. Every pixel of rock, sand, water, lava, steam, ice and metal is real
matter that melts, floods, freezes, burns, sets, cracks and collapses on its own. Nothing is
scripted, so the solutions are yours to find and every disaster plays out differently.
Underneath it runs a hybrid simulation: a cellular-automata grid for terrain and granular
materials, coupled to a Position Based Fluids solver for true liquids and gases. Lava that
meets water flashes to steam and freezes into obsidian. Cut the base out of a tower and it
pancakes into rubble you can then bury or melt.
All the powers of the earth
You play MOLTYN, a volcano professor who leaned in for a closer look, fell in, and came out
the other side with, for reasons the volcano never explains, every power of the earth. You
fly, you fire a laser, and you earn more powers across the story: LAVA, WATER,
LAVA, WIND, STORM, GRAVITY, FREEZE, and a last-resort NUKE (and LAVA).
Two ways to play
Story an 18-mission, five-chapter campaign. A volcano makes a superhero by
accident, and his first job is cleaning up his own arrival. From there the disasters escalate:
fire that breeds, acid that eats dams, storms with a grudge, and finally eruptions that learn
to walk and wade ashore. Missions grade your work instead of failing you, and the score is
always the collateral: what the town lost while you were saving it.
Sandbox free play in generated worlds, or a blank canvas. Pick a volcanic island,
a coastal city, a frozen world or an ocean trench, then do as you please with full powers and
no fail state. Paint terrain, pour fluids, trigger reactions, and level the lot.
Fight things the size of a skyline
The kaiju are not monsters. They are eruptions that learned to walk: deep terrain animated by
pressure, glowing at the seams. You fight them like geology. Strip the armour with heat, freeze
a leg to stagger it, rip loosened plates off with gravity, and put the core out. Each one is a
multi-phase fight against something that is actively eating the town while you work.
A warm, funny world
Under the destruction sits a comedy told in council correspondence: a mayor who files you under
weather, an insurance industry that reclassifies you as an Act of God, cats that must be rescued
and will invoice you for it, and a dog that barks at monsters it believes it could take. It is
a superhero story with a small-town heart and a very long repair bill.
Built to be trusted
Accessible adjustable screen shake, a photosensitivity safeguard that caps flash
intensity and rate-limits strobe effects, a damage assist, a colour-blind-safe hazard palette,
full controller support including controller-only menus, and UI scaling with a readability
floor.
Native and light a pixel-art world that runs on modest hardware, with a bespoke
synthesised soundtrack and no fluff.
MOLTYN is in active development and heading to Early Access. Wishlist to follow along and be
