Alien: Isolation is a widely praised horror game and arguably one of the best titles based on the Alien franchise. However, the game has been criticised for its length, and if you’re wondering how far you are into the game or simply how long you have left, it may be a good idea to see how many missions are in Alien: Isolation and what they involve with our guide below. Please note, there will be spoilers in this guide.
Alien: Isolation Mission List
There are a total of eighteen missions in Alien: Isolation, all of which vary in length and difficulty. Many players find the beginning of the game somewhat easier, encounter a difficulty spike when first facing the Xenomorph, and then encounter another difficulty spike just before the game’s halfway point, although it’s usually smooth sailing towards the end of the game.
1: Closing The Book
Closing The Book is the first mission in Alien: Isolation and it sees you explore the Torrens as it heads towards Sevastopol, a freeport space station operated by Seegson. You’ll meet several crew members and gain a basic understanding of the game.
2: Welcome To Sevastopol
The second mission is Welcome To Sevastopol in which you board the Sevastopol and must make your way through the abandoned station while trying to piece together what has happened.
Encounters is the third mission in Alien: Isolation and it follows Ripley as she disables security lockdown and comes face to face with the alien.
4: Seegson Communications
Seegson Communications is the next mission in the game, which sees you continue exploring Sevastopol with the new Motion Tracker tool.
5: The Quarantine

In Haven, you’ll need to acquire the Blowtorch tool to proceed through the game and help one of your injured crewmates.
In mission nine, Beacon, you take a break from playing as Amanda Ripley and instead follow Marlow on planet LV426 to discover how the Xenomorph landed on the Sevastopol.
10: The Trap
The next mission is The Trap, where you work with other allies to contain and trap the Xenomorph and eject it off the station.

14: The Descent
In The Descent, you as Amanada leave Apollo and must explore the Reactor Core and the Xenomorph nest, where you’ll need to avoid several aliens.
15: The Message
In The Message, the fifteenth mission of Alien: Isolation, you must track down Marlow who has made his way back to his ship, The Anesidora, with Taylor.
Transmission is the sixteenth mission in Alien: Isolation, and it sees you make your way to the communications antenna, located outside Sevastopol.
The penultimate mission of Alien: Isolation is Desolation, wherein you must make your way through the penthouse area of the station to reach the Spaceflight Terminal, facing more aliens along the way.

We hope our Alien: Isolation mission list helps you work out where you are into the game and how long you have left of the exciting and griping title.
How long is Alien: Isolation?
The main campaign of Alien: Isolation takes around 19 hours to complete, depending on the difficulty and your struggle against some of the game’s obstacles and enemies.
Is Alien: Isolation difficult?
Alien: Isolation can be difficult, as the game’s objective is to avoid enemies, rather than facing them, and you have little to no tools in defending yourself, usually meaning instance death. Thankfully, there are several difficulty options, allowing you to customise the game to however challenging you want.
Are there any Alien: Isolation missions without aliens?
*SPOILERS* Yes! The first, eighth, ninth, eleventh, twelfth, and thirteenth missions do not have any aliens. The other missions either have a fully active alien or an alien that crawls around the airvents and can attack.
