Alien: Isolation features a robust achievement system that rewards players for several accomplishments, from completing story missions to discovering hidden collectibles and mastering survival techniques. This guide will help you unlock every achievement available on PC, PS4, Xbox One, Nintendo Switch, PS3, and Xbox 360.
Story Achievements
The majority of achievements are tied to progressing through the game's 19 story missions. Simply completing each mission will unlock associated achievements. For example, finishing the first mission, "Closing the Book," will grant you an achievement. Similarly, completing "Welcome to Sevastopol" and "Encounters" will unlock their respective achievements. While these are straightforward, keep an eye out for optional objectives or specific actions within missions that might unlock bonus achievements.
Collectible Achievements
Alien: Isolation is packed with collectibles, including Archive Logs and ID Tags. Many achievements are awarded for finding a certain number of these items. For instance, you'll find Archive Logs in missions like "Closing the Book" (3 logs) and "Encounters" (4 logs), and ID Tags in "Encounters" (3 tags). The "Welcome to Sevastopol" mission alone contains a sificant 15 Archive Logs and 2 ID Tags. A comprehensive collectible guide is essential for tracking down every last item to unlock these achievements.
Survival and Stealth Achievements
Beyond story progression and collectibles, many achievements focus on your ability to survive and evade the Xenomorph and hostile humans. These might include achievements for remaining undetected for extended periods, using specific tools like the noisemaker or flare to distract enemies, or successfully hiding in lockers or vents. Mastering stealth is key, and certain achievements will specifically reward players who excel at it.
Combat and Tool Usage Achievements
While direct combat against the Alien is generally ill-advised, you will encounter Working Joes and hostile human survivors who can be engaged. Achievements may be awarded for using specific weapons like the revolver or shotgun effectively, or for using tools like the stun baton or EMP mines to incapacitate enemies. Learning the strengths and weaknesses of each enemy type and the tools at your disposal is crucial for unlocking these combat-oriented achievements.
Difficulty and Challenge Achievements
Alien: Isolation offers multiple difficulty settings, and some achievements may be tied to completing the game on higher difficulties, such as Nightmare mode. These achievements demand a deep understanding of the game's mechanics, enemy behaviors, and resource management. Additionally, there might be achievements for completing specific sections of the game without raising an alarm or without being detected by the Alien.
