遊戲入面異形嘅人工智慧俾設定為利用視覺、聲音同埋嗅覺嚟追住主角而唔係依照固定嘅路線巡邏。異形嘅人工智慧包含多組複雜嘅行為模式，將隨著遊戲嘅進行逐漸開啟，產生異形喺接觸玩者嘅過程入面亦逐漸識得成長。異形具有調查「次要存在證據」嘅能力，例如喺注意到個置物櫃或氣壓鎖俾人開咗，牠就會搵個開啟者。玩者可奔跑嚟增加移動速度，但腳步聲會引起異形嘅注意。玩者持有手電筒和可追蹤異形動作的偵測器，但使用時產生的光線和聲響會讓異形更容易找到玩者藏身嘅位置。玩者可匿喺桌子底下或置物櫃等空間入面，呢個時候可能需要㩒住遊戲操作器嘅掣嚟避免發出呼吸聲。遊戲嘅關卡採用非線性設計，每個空間都有多個出入點，為玩者同異形提供唔同嘅攻擊同逃亡路線。
In the game, the Alien's artificial intelligence is set to use sight, sound, and smell to chase the protagonist rather than follow a fixed route. The artificial intelligence of the alien contains multiple sets of complex behavior patterns, which will gradually open as the game progresses, and the alien will gradually learn to grow in the process of contacting the player. The Xenomorph has the ability to investigate "evidence of secondary existence", such as finding someone to open a locker or barometric lock. The player can run to increase their movement speed, but the sound of footsteps will attract the attention of the aliens. The player is armed with a flashlight and an observer that tracks the movements of the alien, but the light and sound generated when used will make it easier for the alien to find where the player is hiding. Players may want to hide under a table or in a locker, where they may need to press the button of the game operator to avoid making a breathing sound. The game's levels are non-linear, with multiple entry and exit points in each space, providing players and Xenomorphs with different attack and escape routes.
