Scientific spaceship Saratorum drifts near the planet Nadalon. An alien craft appears out of nowhere. All attempts at communication fail. Time passes, and crew members, one after another, start to act weird. It was already too late when you gathered your courage and decided to act. Now only your weapon can help you warn your Homeworld about the alien threat. Inspired by Zero Tolerance and classic retro shooters: • 5 inventory slots to manage your equipment • A wide selection of weapons • Levels that demand different approaches and tools to complete - sometimes speed, sometimes caution, sometimes special gear • Bosses and enemies with unique weaknesses and tactics • Cutscenes connecting levels with the storyline Originally made for PSP in 2025. Full PC Steam port to modern systems. 


Notes: You need to shoot enemies and they have blood. But the storyline they are your crew members possessed by aliens
