MOLTYN Demo

Melt the city. Flood it. Nuke it!

Spray lava off the crater rim and it runs down the mountain into town. Cut the supports out of a tower and it pancakes into rubble you can bury, melt or pick up and throw. Flood a street and the water works its way down through the floors and sits at its own level, one storey at a time.

None of that is a set piece. Nothing on screen is 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.

This is the free demo: the real engine, the real physics and the real hero. Four story missions, the island to yourself for as long as you like, and a few practice scenes on the side.

Four story missions

AFTER HOURS. Something is dug in under the harbour district and the city is the shield. Hold the streets, then tunnel down and take out the command unit.

KAIJU ATTACK! An eruption that learned to walk comes in off the breakwater. Kill the escorts that hold its shield up, then bring it down by any means necessary, before it lasers the entire city!

SHADOW MOLTYN. Something climbed out of the volcano after you, and it looks like you. Same powers, same matter. Handsome guy really.

STARFALL. The sky is falling on the city and you are the only thing between the two. Break the meteors up any way you want, just try to keep the skyline standing.

Missions can be lost. Every one ends on a report card that leads with how much of the city is still standing, so the real score is what the town paid for your rescue.

The island sandbox

A cold open in a destructible office. MOLTYN presents his own abilities on the wall screen, which doubles as the controls tutorial. Hold to skip it, or laser the screen off the wall and the pitch dies with it. The room is yours to wreck and it is fully simulated like everything else.

The island. A volcano island, ocean on both sides, and a hillside town running down to the harbour: office blocks, high-rise, walk-ups, houses, a lighthouse, a subway with a real train in it, would be a shame if someone messed it up for no good reason!

Seven powers. Laser, gravity, water, lava, storm, freeze, and a nuke. On a world that genuinely reacts: lava meeting water makes obsidian and steam, a building that loses its supports pancakes, thrown matter lands and stays where it lands.

Enemies, if you want them. Wasp waves from the sky and heavier things on the ground, switchable on or off. They take damage as matter, not as a flashing sprite.

No timer, no fail state. Get knocked down and you get back up. Reset the island whenever you like.
