About Alien Quarantine

Alien Quarantine is a top-down shooter set inside a research station that has been overtaken by alien life. Across 20 missions, you move through deeper parts of the station while fighting changing alien types with distinct attacks and visual designs.

Each mission presents three waves that become more demanding, followed by a special boss encounter. Survival is only part of the work: objectives include restoring power consoles, rescuing crew, recovering samples, and securing evacuation routes. The mix of shooting and station tasks gives each mission a practical purpose beyond clearing enemies.

How to Play Alien Quarantine

Use WASD or the arrow keys to move around the station, and aim with the mouse. On touchscreen devices, use the displayed movement, firing, grenade, and interaction controls.

Press the left mouse button to fire and the right mouse button to throw a grenade. Press E near consoles or relevant objects to use them, collect items, and activate exits.

Work through three enemy waves, then face the distinct boss assigned to that mission. Esc pauses the game when you need to stop.

Tips & Tricks

1Keep moving while aliens attack, because the station enemies use different attack patterns from sector to sector and enemy fire must be avoided.
2Use grenades for moments when firing alone is not enough, but keep the interaction key ready for consoles, items, and exits that are part of your objectives.
3Check the mission task before leaving an area: restoring power, helping crew, finding samples, and opening evacuation routes each require different actions.
