When evil aliens invade the galaxy, it is up to you and your fleet of decommissioned starfighters to drive them back. Pilot your humble thrust ship through tense battles and tight spaces. Hone your piloting skills, rescue survivors, blow up gobs of baddies, witness the horrors that lurk in the darkest corners of the galaxy, and make it out alive.
Retrobooster is a 2.5D survival shooter and cave-flyer, focusing on skill-based flying and enemy blasting. It combines old school gameplay with contemporary graphics and audio. Retrobooster also has speed-flying challenges, various weapons, puzzles, juicy monsters, a warped sense of humor, and a healthy dose of bullet hell action. Survive to the end if you can, and use your new flying skills to replay for high scores.
