About Alien Quarantine
Alien Quarantine drops you right into the corridors of an infected space research outpost. As hostile lifeforms spread across every sector, your mission is to explore each danger zone, rescue surviving crew members, restore key power systems, and collect valuable samples before moving on to safety.
Every stage challenges you to withstand three intensifying waves of alien enemies with distinct attacks, culminating in a showdown against a powerful boss. Advance through all twenty levels in landscape view, utilize your weapons and grenades wisely, and secure an escape route deeper into the facility.
