In Alien Isolation for the PS4, The player has the ability to crouch to hide behind objects to break line of sight with the Alien, and the player can then covertly peek over or lean around to gain view. The player can also run and possesses both a flashlight and a motion tracker to detect the Alien's movements. However, using any of these creates noise or light, which increases the chance of the Alien finding the player. The player can go under tables or inside lockers to hide from the Alien, and will sometimes have to make Amanda hold her breath to avoid making noise. Levels are designed to be non-linear, with multiple entry and exit points for each room providing alternative routes for the Alien to attack or the player to escape.
The game has a minimal heads-up display, instead requiring the player to use their inventory to acquire information, such as bringing up the motion tracker to locate the Alien. Using the motion tracker triggers a depth of field effect so the player can focus on either the tracker or what is in front, but cannot focus on both at the same time which may be frustrating to some player. The motion tracker is only capable of detecting the Alien's approximate location when it is moving; it can neither detect the Alien's specific location nor locate the Alien when it is not moving. The game features a crafting system which allows the player to create weapons and tools to defend themselves. Crafting objects appear in randomized locations, forcing players to explore the level.
The game features a minimal amount of music, relying more on ambient sound to make the player notice what may be happening and to also enhance the "scary" atmosphere. However, there are some scripted sequences of music, as well as rising noise whenever the Alien may be nearby and ready to attack you. Recently it was announced that two pieces of pre-order downloadable content. All pre-orders received a free upgrade to the Nostromo Edition, which includes the Crew Expendable mission featuring the original crew of the Nostromo. By ordering the Ripley Edition from selected retailers, players received the Last Survivor mission, which features Ellen Ripley attempting to set the self-destruct system and escape aboard the Narcissus.
