"Space Ship Infinity" is a retro-style, fast-paced arcade shoot 'em up game where you avoid colliding with enemies while constantly moving and firing. The game features easy-to-learn controls, with keyboard and mouse support, and offers initial power-ups like Triple Shot, Double Points, and Healer. Your ship can be upgraded for speed, health, and damage, and collecting coins allows you to unlock additional power-ups and upgrades as you chase the best score in infinite survival mode.
