How many GB is Alien: Isolation - Last Survivor?

35 GB

That makes it bigger than 93% of Adventure games we have measured.

The median Adventure game needs 3 GB; the largest tenth start at 25 GB.

Leave at least 47 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

As Ellen Ripley, it is down to you to complete the last mission on board the Nostromo. The rest of the crew are dead. In a desperate bid to survive you must set the ship’s self-destruct and attempt to reach the escape shuttle.
