The latest Stalker 2 update introduces deeper AI simulation, quality-of-life improvements, and new weapons - including the Three-Line Rifle and Kora handgun. Here’s everything added in Patch 1.5.

GSC Game World's post-apocalyptic shooter Stalker 2: Heart of Chornobyl has received a significant update with the release of Patch 1.5, which is now live on Steam. The patch introduces a wide range of improvements, including changes to the game’s A-Life system, loot mechanics, and new gear like the Three-Line Rifle and Kora handgun.

The biggest highlight is certainly a feature that will allow players to loot mutant corpses and get trophies, which they can then sell at vendors. This was one of the features that the community has been requesting since the launch, and it's nice to see that GSC Game World finally delivered.

Stalker 2 Patch 1.5 Highlights 

A-Life Overhaul – A More Dynamic Zone

The A-Life simulation system has received a major upgrade, making the world of Stalker 2 feel more reactive and immersive:

  • All NPCs are now simulated, even outside the player’s view. Stalkers and mutants continue to move, interact, and survive in the Zone, adding a deeper layer of realism.
  • Characters won’t respawn directly in front of players. Instead, they now reappear out of sight, preventing immersion-breaking pop-ins.
  • The visualization range has been slightly increased, with better animations and weapon visibility when NPCs appear.
  • Expect to run into familiar faces. Surviving stalkers may be encountered again during your travels.

New Gear and Features

  • Added new anomaly: Water Electric Tornado.
  • Added Three-Line Rifle weapon.
  • Added new handgun Kora.
  • Added the new feature: looting of mutant parts.
  • Added displaying of available artefact slots for armours in the Upgrade tab.
  • The player stash window is increased in size.
  • Fixed an issue when the "Take all" button becomes inactive after putting any item to the loot window.
  • 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.

All in all, this is another gargantuan and excellent patch for Stalker 2, which is shaping up into a mega game, after all those launch issues. Even back then, Stalker 2 was one of the most immersive gaming experiences I've ever had, and with all these fixes, it's only got better.
