Stalker 2: Heart of Chornobyl, the long-awaited and highly acclaimed first-person survival shooter, has received a new big update called Patch 1.5.
Much like the previous update, Patch 1.4, Patch 1.5 aims to improve the AI and A Life of all NPCs and enemies while implementing quality-of-life improvements, balance changes, bug fixes, new gear to find, new enemies to kill, and more.
The key method this update plans to improve AI for all NPCs is by making them simulated all the time, even outside the player's view.
This will allow the NPCs to behave like they did in STALKER: Shadow of Chernobyl (which was recently remastered along with the original Stalker trilogy), and live out their lives in more realistic ways outside of quests or interacting with the player.
As the full list of patch notes for Patch 1.5 is too many to list here (you can find them on the game's official website), here are the major content highlights for Stalker 2: Heart of Chornobyl's Patch 1.5 as taken from the game's Steam page.
Be warned, some of these patch notes will contain story spoilers.

Stalker 2: Heart of Chornobyl Patch 1.5 notes
Highlights
- A-Life changes
- Life in the Zone is now simulated for all characters, not just those in the player's view.
- Characters continue to live their lives and pursue their goals in the Zone until they meet their end.
- The player can meet the same stalkers after some time.
- Players may encounter more A-Life characters resting or interacting in various locations, adding to the world’s immersion.
- Characters will no longer respawn directly in front of the player. When the player clears the mutants' lair, for example, those mutants won't simply reappear moments later.
- A-Life Director will no longer respawn characters at the edge of visualization. Instead, respawn moved further away from the player, while maintaining the Zone's population.
- Visualization range is slightly increased. Characters now appear in visualization range with relevant animations and equipped weapons. This reduces the "pop-in" effect and contributes to a more seamless character visualization.

- Added new handgun Kora.
- Added the new feature: looting of mutant parts.
- Added displaying of available artifact slots for armors in the Upgrade tab.

- Added unlockable "Fix all" button in the technician's upgrade menu, to repair all equipped gear.
- Added reload renewal feature for all of the weapons.

GSC Game World continues to refine this long-awaited title to help reach its full potential
Fans have been requesting that the AI for friendly NPCs and enemies function like in the original STALKER: Shadow of Chernobyl long before A-Life was beginning to get fixed, back when Patch 1.2 launched.
This is because before, the A-Life for NPCs and enemies was broken in Stalker 2. Characters would behave in weird ways, NPCs and enemies would despawn randomly, and NPC and enemies would frequently only spawn next to the player, just to name a few of the issues.
Despite this, Stalker 2 would go on to earn many positive reviews (including a glowing 4/5 review from us at Windows Central) and continue to receive many updates, which have been fixing the game's tech problems it had at launch.
Hopefully, with this Patch 1.5 update, the new simulated AI for NPCs and enemies will meet fans' expectations and help them be more fully immersed in the ruined yet beautiful world of Stalker 2.
STALKER 2 is available for purchase on Xbox Series X|S and PC via Windows and Steam. It is also available on the Xbox Game Pass library, allowing Xbox Game Pass Ultimate subscribers to play it on Xbox, PC, and Xbox Cloud Gaming.
