Taiwanese publisher Mango Party has announced that Starbreed, an adult 3D rail shooter developed by RegulusNSFW, launches on Steam on July 31. It welds the arcade rush of a rail shooter onto dating-sim progression: clear a stage, unlock a new crew member, flirt your way to better ship upgrades, and the two systems keep feeding each other
Content notice: the protagonist is a hermaphrodite, and the H-content includes futanari material. Please use your own discretion

A Hermaphrodite Protagonist, With H-Scenes Written for Both Forms
The defining feature here sits with the protagonist: a hermaphrodite by design, able to switch between female and male forms. This goes past cosmetics. The game authors separate H-scenes for each form, so the same crew member and the same relationship play out differently depending on which body you take into the scene
Stat allocation follows the same axis. Dominance raises boost-energy regeneration and makes your masculine side more attractive; Will raises maximum HP and makes your feminine side more attractive. How you spend points is effectively a decision about which direction the protagonist grows

Beyond the protagonist’s own two forms, certain crew members may strike sparks with each other. Raise affinity step by step and earn the title of Starbreed
Eight Stages, Each Planet With Its Own Terrain and Boss
The game runs eight stages, and every planet brings its own terrain, enemy layouts and a unique boss fight. Low-altitude pursuit over a coastal city, high-speed weaving through neon districts, a parasite nest deep in a cavern, an ambush along a jungle river: the scenery swings hard between them






Save the planets, recruit allies, and push on toward the final battle



Mix and Match Crew and Weapons
Every crew member carries their own active and passive abilities, and calling in support at the right moment is often the difference between a clear and a wipe. Primary and secondary weapons offer plenty of pairings too: the energy cannon suits single targets, missiles handle crowds, and the loadout is yours to build around your own style


Each new ally you unlock grants a matching active and passive ability. Bring them into the squad, raise affinity, and unlock fully animated adult content along the way


Over 40 Fully Animated H-Scenes
Counting the protagonist, the game features 8 characters. Hit enough affinity or clear specific conditions and new adult scenes open up, adding to a total of more than 40 fully animated H-scenes waiting to be found
