About This Game

The Last Sideran is a fast 2D arcade shoot 'em up about survival, high scores, and the last light of a vanished people, with hand-drawn 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.

Arcade Survival

Every run is built for pressure: dodge, shoot, collect, recover, and push for a higher score. Stages grow increasingly dangerous as hazards, swarming Spikes, and bosses force you to keep moving.

Unlock New Ships

Earn star essence to unlock six ships, each with its own combat style. Take the Navy Interceptor, Desert Raider, Pirate Corsair, Volcanic Warship, Cybernetic Runner, or Celestial Dragon into a run and find the one that fits you. Forward lasers, shotgun bursts, dual cannons, drone support, explosive weapons, 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.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some artwork used in The Last Sideran and its Steam/store marketing materials was created with the help of generative AI tools during development. Those assets were reviewed and refined by hand to match the game's visual style. The game does not use live-generated AI during play. The design, story, code, and music are human-made.

Mature Content Description

The developers describe the content like this:

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.
