The game
Clockwork automatons, steam colossi and steam zeppelins want to steal the aether cores from your core chamber and carry them out through the gate. If a carrier is destroyed, the core drops and rolls back to the chamber. The match is lost once all 20 cores have left the field.
Towers occupy tiles, and enemies find their way around them. This creates a maze that lengthens their path. You may not block it completely. Flying enemies ignore the maze.

The towers
Every tower has three upgrade levels. Values from level 1 to 3; pictures show level 3.
Gatling
Cheap and fast, hits ground and air.
Cost 100 · Range 3–3.7 tiles · Damage 7–20 per hit · 5 shots/s · ground + air
Flamethrower
A ring of fire from the pressure boiler: burns every ground enemy at short range. Weak against armor.

Tesla coil
Chain lightning that jumps between several enemies. Ground and air.
Cost 175 · Range 2.4–2.9 tiles · Damage 40–130 per hit · every 1.2 s · jumps to 3–6 enemies · ground + air
Chronoworks
A massive clockwork slows time for every enemy in range. No damage.
Cost 125 · Range 2.5–3.1 tiles · slows by 35–62 % · ground + air
Field cannon
Long range, powerful single shots. Ground only, not right next to it.
Cost 250 · Range 6–8 tiles · Damage 90–300 per hit · every 2 s · not closer than 1.5 tiles · ground only
Steam mortar
Glowing shells in a high arc. Huge range, area damage, slow, ground only.
Cost 300 · Range 7–9 tiles · Damage 80–240 per hit · every 4 s · Area damage 1.3 tiles · ground only

Homing steam rockets against zeppelins. Air only.
Cost 200 · Range 5–6 tiles · Damage 60–190 per hit · every 1.2 s · air only
The enemies
Clockwork walker
A wound-up brass automaton marching stubbornly to the core chamber.
Health 50 · Speed 1.3 tiles/s · Bounty 9 gold
Tip: A solid average enemy: every tower can handle it.
Wind-up beetle
A nimble copper beetle that comes in large swarms.
Health 22 · Speed 2.3 tiles/s · Bounty 4 gold
Tip: Flamethrower, Tesla coil and steam mortar hit many at once.
Steam colossus
An armored steam boiler on four stomping legs.
Health 260 · Speed 0.85 tiles/s · Armor 6 · Bounty 28 gold
Tip: Armor soaks up small hits: use the field cannon and steam mortar; Gatling and flames are weak.
Aether automaton
A floating porcelain bell with an aether shield that recharges after a short time.
Health 90 · Speed 1.1 tiles/s · Aether shield 110 · Bounty 20 gold
Tip: The steam hammer shatters shields with four times the force.
Steam zeppelin
An airship with a steam-driven gondola that simply floats over your maze.
Health 70 · Speed 1.6 tiles/s · flies · Bounty 13 gold
Tip: Only the Gatling, Tesla coil, Chronoworks and harpoon launcher can reach it.
Strider colossus
A three-legged colossus with heavy armor, cannons and smoking stacks.
Health 2200 · Speed 0.6 tiles/s · Armor 10 · Bounty 250 gold
Tip: Focus everything: field cannons and mortars for damage, the Chronoworks to slow it down.
