Cogspire: Siege of the Amber Skies
“Every tower is a gadget you invent.”
Defend a floating clockwork city from a sky armada by building and upgrading brass towers along its sky-bridges.
Cozy workshops against a sky full of smoke and iron. Merge salvaged parts in the workshop to unlock new tower designs.
Design Pillars
Above a world choked in coal smoke floats Cogspire, the last clean city in the sky: a stack of copper towers, gear-driven bridges and clock faces, held aloft by the Amber Heart, a giant living crystal of warm light that powers every engine in the city.
Below the clouds rule the Soot Barons. They burned the ground world black to feed their factories. Now their fleet, the Soot Armada, rises through the smog to rip the Amber Heart out of Cogspire and burn it in their furnaces.
Pick Garrick, the heavy hitter, or Wren, the quick builder, and use their active skill during each wave.
A brutal, battle-hardened 40-year-old sky engineer and the Inventors' Guild's last line of defense. Huge and broad-shouldered, with a shaved head, short dark beard and a heavy scar across his face.
Brass goggles, a scorched leather coat with riveted copper shoulder plates and a mechanical brass gauntlet on his right arm. He flies on a heavy steampunk jetpack with two copper thruster engines. His companion is Tick, a small clockwork hawk with one glowing amber eye, which spots incoming ships.
A confident 24-year-old airship engineer and the youngest member of the Inventors' Guild. Wavy auburn hair in a messy bun, brass goggles, a patched brown leather flight jacket and a tool belt full of wrenches.
She flies a small winged copper glider pack. Her companion is Cog, a palm-sized clockwork owl with big amber glass eyes, built by her late father. Where Garrick is the heavy hitter, Wren is the quick builder: faster tower upgrades and repairs.
Towers are built on brass platforms along the sky lanes and upgraded through three tiers.
The flagship of the Soot Armada, a dreadnought the size of a city district. Its prow is a giant furnace mouth with glowing grates like teeth; its hull is black riveted iron covered in smokestacks and cannons.
The Iron Maw is always bigger than the frame.

Stylized 2.5D mobile game art in the look of a polished platformer. Mood: cozy inventive warmth against an epic smoky threat. Warm lighting from lamps and amber crystals, golden-hour light through smoke, floating sparks and steam puffs.
- Round, chunky and friendly for the city and the Guild; heavy, angular and spiky for the Soot Armada.
- Robots and creatures have big heads (about 1:2). Garrick: heavy heroic proportions, serious and tough, never cute.
- Thick soot-black outlines on characters, towers and items. None on backgrounds.
- Three depth layers: sharp foreground gadgets, midground copper towers and bridges, hazy clouds and smoke.
- Warm amber light means friendly and powered; red-orange furnace glow means enemy.
- Avoid gore, grimdark rust, cold blues, neon and tiny details.
