From the developer
Survive 20 missions in Alien Quarantine, a sci-fi top-down shooter set aboard a research station overrun by alien life. Clear three escalating waves, dodge enemy fire, and defeat a unique, larger boss at the end of every level. Alien types and visual designs change from sector to sector, each with distinct attacks.
Restore power consoles, rescue crew, recover samples, secure evacuation routes, and descend deeper into the station. Web Dev https://www.arcadegames.com.es/
