Content notice: The game contains stylized characters in revealing but fully clothed outfits, discussion about ending reproduction and no longer having children, and ending symbolism that may resemble an egg and sperm without depicting sex. The introduction contains dialogue referring to torture. Unlockable classroom and assessment stories discuss hypothetical actions or past events involving the possible killing of a teenage character, increasing her prescribed pain-medication therapy, and possibly “putting her away” so she becomes like everyone else, suggesting institutional confinement and forced conformity. The stories also discuss morality, responsibility, blame, and evil. All references to killing, torture, medical harm, or harm to minors occur only in dialogue; the game never visually depicts anyone being tortured, killed, or medically harmed. The game contains no nudity, sexual acts, sexual stimulation, or masturbation.

About this game
About This Game
The Last Sideran is a fast 2D arcade shoot 'em up about survival, defiance, and the last light of a vanished people, with sci-fi visuals and select stylized 3D elements.
You play as Zenia, the last Sideran. Her people are gone, but the machines built to watch and control them still remain: the Spikes, relentless hunters that fill the screen with danger. Gather star essence to stay alive, chase it into risky spaces, and seize weapon power-ups when a run gives you the chance.
Four modes share the same tight arcade core; play it as a campaign, a pure score chase, or a race against a draining clock.
Career
Zenia's story unfolds across five chapters as you climb levels, survive key encounters, and defeat bosses. Unlock ships, uncover the truth about the Siderans and the Spikes, and follow her all the way to Rebirth.
New Game+
Finish Career and begin again at Level 7 with everything you earned, pushing beyond Rebirth into the run's hardest stretch.
Arcade
The original score-chasing run. No story gates, no permanent upgrades — just escalating stages and how far your reflexes carry you.
Essence Rush
Time is Zenia's life. The clock drains every second you fly; star essence buys it back and every hit takes it away. No shields, no extra lives, and a score table of its own.
Unlock New Ships
Every run starts with the Navy Interceptor. Collect star essence to unlock five more ships, each with its own weapons and combat style. When you reach a new stage, your ship changes to a random unlocked one. The game goes through the full lineup before repeating a ship. Across the six ships, you'll use forward lasers, shotgun blasts, dual cannons, support drones, explosives, and more.
Career Mode
Zenia's story unfolds as you reach major milestones, survive key encounters, and defeat bosses. Push farther to uncover the truth about the Siderans, the Spikes, and what remains after the fall.

Zenia’s opening is new, the guns hit harder, and the Cybernetic Runner no longer
What’s new • New intro menu. A more mythical opening before you start a run; the void, Zenia, and the last light of the Siderans. • Weapon upgrades. Power-ups have more punch and a clearer feel in combat. • Cybernetic Runner. Signature bombs now fire with the weapon power-up, not instead of it. Grab Plasma Comet, Crescent Round, or another upgrade and you still drop both mines.Read full article on Community Announcements (PixelDoDev)Patch NotesOfficial
Aug 11 release notes
What’s New Every run now begins with the Navy Interceptor, the ship Zenia first escaped in. At each new level, the game randomly switches to another unlocked ship. All available ships will appear before the random rotation repeats. Fish Swarms and Jellyfish Blooms now alternate during a run. Difficulty options are now labeled Easy, Normal, and Hard. Fixed an issue where an in-app purchase could remain on “Loading” and not activate until the game was restarted. Additional stability improvements and bug fixes.Read full article on Community Announcements (PixelDoDev)Patch NotesOfficial
New weapons and improvements
Release Notes This update introduces new weapon effects and reworks Green Eyes performance without sacrificing the encounter’s signature swarm. New Weapons Added the Flower Round, a procedural spinning projectile with sharp, weapon-like petals. After leaving Zenia’s gun, the flower releases its petals one at a time in multiple directions. Direct contact cancels the flower and deals impact damage. Increased the Flower Round’s firing speed slightly. Redesigned the fast round as a distinct procedural circular projectile for clearer identification during combat. Green Eyes Improvements Restored the complete 210-eye formation at every performance level. Removed the system that reduced the number of Green Eyes when frame rate dropped. Reduced how many eyes can fire simultaneously. Added an adaptive cap for active Green Eye projectiles. Slower hardware now reduces projectile frequency, glow effects, pupil animation, and background movement instead of removing enemies. Optimized the 300-star boss background by lowering its animation frequency when performance struggles. Quality and Stability Updated automated coverage for the new weapons and Green Eyes performance behavior. Verified the complete project with 107 passing tests.Read full article on Community Announcements (PixelDoDev)
