Third Law

Every action has an equal and opposite reaction.

The orbital greenhouse Hesperides has been overgrown by the Bloom, an alien plant that came aboard with a meteor sample. The spin drive is dead, so there is no up. Your suit jets are nearly dry. But every gun you own kicks like a mule.

Shoot behind you to fly forward. Blast the floor with the Scattergun to jump. Let the Mulcher's recoil carry you like a jetpack. Rocket-ride your own seed bombs. Fire the Spade and get thrown across the room. And the faster you fly, the harder you hit.

• Recoil is movement — five guns, five ways to fly: Pruner, Scattergun, Mulcher, Seeder and the rail-driving Spade. Plus your fists: punch creatures away and punch yourself off walls. A recharging boost for when you need to get out fast.
• Speed is damage — a kinetic multiplier rewards you for staying fast.
• A campaign of twenty levels across five sectors — hydroponics, a floating orchard, a forest under glass, a frozen seed vault and the sun core. Pick any unlocked level on the station map and earn up to three stars in each.
• Every level is its own job — clear the waves, defend the seed core, collect golden seeds, race the airlock, burst root nodes, survive the blackout, shoot the smothered grow lamps back on, chase down a seed thief.
• Every level has its own twist — rocket-riding gas canisters, exploding fruit, rotor arms, wind tunnels, sunbeams that burn the Bloom, cryo vents, gravity surges, hull breaches, solar flares. Fight out on the hull above the Earth, and inside the beating heart of the Bloom itself.
• Five bosses — the Rootmother, Queen Pollen, Ladon the garden dragon, the Archivist and the Golden Apple.
• Thirteen Bloom creatures — spores that pop on their friends, armoured burrs that bonk themselves on walls, snapjaws growing from the walls, leech moths that land on your visor (punch them off!).
• The Workshop — weapons you find are yours to keep. Spend seeds on 26 permanent suit and weapon upgrades and 10 perks; stars open more perk slots. Six suits to unlock.
• The Ark — an endless run through the Bloom's seed ship: deck after deck, harder every time, a boss every fifth deck and supply caches with run-only upgrades in between.
• A comic book in zero g — ligne claire ink lines, flat colours, halftone and big sound words: SPLORCH! KA-POP! POW!
• A 1970s space synthesizer score, generated live, with a battle layer that rises with the fighting.
• Rebindable keys, full gamepad support, five languages — English, Deutsch, Español, Русский, 中文.
• Everything — every model, sound and note — is made by code at runtime.
