The game Alien: Isolation focuses on stealth mechanics and features few aliens throughout, requiring players to go unnoticed to survive the hunt. Players will encounter humans and androids, but shooting is not their primary concern. Increasing light or sound makes it easier to be detected. The most exciting aspect of the game is the alien's artificial intelligence, which detects the protagonist and adapts to their behavior.

The non-linear level structure includes multiple points of exit and entry, but you will not be able to track the alien's specific location. The game does not have an on-screen HUD, making your attention the most crucial element when using your inventory items.

Alien: Isolation also features a crafting system that allows players to create weapons and tools for defense. Crafting items appear in random locations, forcing players to explore to find them in each playthrough.
