Motion Tracker

Use the tracker wisely and remove it as soon as it detects motion.

In Alien: Isolation, the motion tracker serves as Amanda Ripley's primary means of detecting the Xenomorph's movements within the chaotic environment of Sevastopol. The tracker shows the Alien's movements, but it cannot detect enemies that are standing still or tell whether the Alien is in the ducts or on the ground level. If the Alien is close enough it is drawn by the tracker's sound, so the player has to use the tracker sparingly.

Lore & Background

The narrative of Sevastopol is defined by the relentless pursuit of the Alien, which begins in earnest after mission five, "The Quarantine." Rather than following a set path, the Alien can investigate disturbances and hunt the player by sight or sound.

Players should utilize the motion tracker to detect the Alien's movements by listening for its sound and watching for directional blips. However, strict discipline is required: if the Alien is close enough, it will be attracted by the device's noise, so players must remove it immediately upon detecting motion. The tracker has specific limitations; it cannot detect enemies that are not moving, nor can it determine if the creature is located in overhead ducts or on the ground level. On the hardest difficulty setting, "Nightmare," these limitations are exacerbated as the tracker becomes unreliable and the in-game mini-map is unavailable entirely. Consequently, players must craft noise makers to distract enemies and use fire weapons to force the Alien to retreat temporarily, relying on stealth rather than direct confrontation.
