Assault on the Iron Fortress — a 3D isometric rail shooter built on Three.js, in the lineage of Zaxxon.

You fly a strike fighter down the trenches of an orbital fortress. The camera sits at a raked isometric angle, which means you cannot tell how high you are by looking at the ship — you read it off the shadow on the deck and the altimeter on the right. Walls have gaps. Some of those gaps are at your altitude and some are not.

Everything you see and hear is generated at runtime.
