Alien Quarantine: station, waves and bosses

In Alien Quarantine, you clear out a research station overrun by alien life in a top-down shooter. Each level has three increasing waves, and at the end a big boss awaits you. Between battles, you restore consoles, save the crew, collect samples and open an escape route.

How to start a mission

  • Don't stand under enemy fire and move along the corridors.
  • Go through three waves in a row until the boss appears.
  • Activate the consoles to restore power and open the exit.

How many missions are there in Alien Quarantine?

There are 20 missions in the campaign. Three waves and a boss on each level - familiar from Zombie Space Episode II. In new sectors you meet different aliens, and their attacks change the route through the station.

What do you do between fights?

You restore consoles, rescue the crew, collect samples and activate exits. These tasks unlock the next step deeper into the station. So you alternate between shooting and short tasks at objects.

How to play

PC:

  • WASD or Arrows - movement around the station
  • Mouse - aiming
  • LMB - shooting
  • RMB - throw grenade
  • E - consoles and outputs
  • Esc - pause
