How AI is used
AI tools helped with the translations, some text drafts, and early concept and 3D work for the logo and asteroid models, which the developer then reworked and finished. Everything was directed and assembled by the developer.
The developer's own words, from Steam.
About Last Star Standing
The aliens have weaponized the asteroids. Frozen comets, burning brutes and storm-charged shards now hunt anything that shines, and one by one the stars are going out. You are the last star standing.
Begin as a lone light bending the fabric of space. Grow into a full solar system: eight worlds in orbit, a belt of captured asteroids turned against their makers, and a view so wide the armada looks like dust. Then take the fight to their commanders.
BUILD YOUR OWN SOLAR SYSTEM
- Pull wandering worlds into orbit, then turn them into Ice, Lava, Storm, Ringed, Iron, Laser or Radio planets. Each one is a weapon of its own.
- Catch the aliens' asteroids with your own gravity and grind them into a belt of dust that shreds the horde.
- Your worlds shield you, but hard enough hits knock them loose. Fight to win them back.
- Every world makes you bigger. Your star swells, space sinks deeper around you, the view pulls back, and bigger enemies arrive to meet you.
SLINGSHOT ACROSS SPACE
Skim a gas giant and its gravity flings you onward. Chain one throw into the next, four or five in a row, and leave the horde far behind. Hit twice your speed and your Speed Shield lights up: ram straight through them.
In the Distant Galaxy the chain ends where you aim it: straight into a black hole, and out into new space.
WEAPONS THAT EVOLVE
- 11 weapons, 23 upgrades and 11 evolutions, from Solar Storm and Hypernova to Absolute Zero, Event Horizon and Music of the Spheres.
- Weapons grow brighter, bigger and wilder with every level.
- Crack open Cosmic Anomalies for a Stellar Fragment, a Nova or a Supernova: 1, 3 or 5 rewards at once. Evolutions only come from Anomalies.
SIX REGIONS OF SPACE, EACH WITH ITS OWN RULES
- Solar System: home space, and something alien watching.
- Distant Galaxy: black holes bend every path. Fall into one and you come out somewhere else.
- Dark Matter: cloaked ships hide in the dark. Only your light reveals them.
- Wormhole: great wormholes drag you away mid-fight and drop you into new space.
- Magnetar Field: a dead star's field lines throw back any star going fast. Chain slingshots, wall bounces and bumpers into combos and jackpots.
- Nebula: radiation drifts after you like something alive, the ground rises into hills, and the giants burn at their cores.
Plus four bonus stages: Gas Giant, Asteroid Field, the Cosmic Rift, where all four kinds of broken space take turns, and the Tesseract, where space folds and turns, carrying you, your enemies and your shots with it.
REAL COSMIC PHENOMENA
A Quasi-Star, a White Hole, the Oh-My-God Particle, the Boötes Void and more wake up as you come near. They're deadly, but steer the horde into them and they fight for you.
HIDDEN KILLBOXES
Ride a stream through a narrow asteroid corridor into a sealed cavern full of waiting enemies. The way in closes behind you, and the only way out is through the elite. Win, and its Nova is yours.
AN ALIEN CHAIN OF COMMAND
Each region's commander outranks the last: Cruiser, Battleship, Shadow Dreadnought, Mothership, The Conductor, The Harvester. Beat the boss early and Overdrive kicks in, and the horde keeps climbing until the clock runs out.
EIGHT STARS, ENDLESS RUNS
- Play as a Yellow Star, Red Giant, Blue Giant, White Dwarf, Neutron Star, Pulsar, Binary Star or Black Hole, each with its own starting weapon and strengths.
- Spend Solar Energy on permanent Power-Ups between runs.
- The horde keeps pace with you: the stronger your build, the harder it pushes back.
- Veterans can take on the Curse for a tougher, richer run.
- 10-minute runs and full controller support.
Warning: this game contains frequent flashing lights and screen shake.
