GSC Game World have released a few minor patches since the release of S.T.A.L.K.E.R. 2: Heart of Chornobyl, but today has seen the biggest one yet released.

Called Patch 1.1.1, sexy I know, this update will address 1800 issues with the game including the first iteration of the A-Life fixes. One thing of note, the patch is very large and will take a while to download, so those hoping to jump in right away might be waiting for a bit.

In terms of fixes though, there are the highlights and the rest, the highlights are called A-Life Fixes here and these are those:

Fixed the issue with spawning NPCs behind the player's back.

• Players can now encounter roaming NPCs across the Zone more often.

• Greatly extended the distance at which A-Life NPCs are visible to the player.

• Fixed the aggressive optimization issue that prevented A-Life NPCs to exist in Offline (out of player's visualization range).

  • In Offline mode, A-Life will continue to advance towards their goals over time.

  • Players may now have opportunities to encounter A-Life NPCs they've previously met by following in the same direction as the NPCs.

• Improved A-Life NPCs navigation in Offline using GameGraph (global AI navigation map):

  • Fixed multiple issues where NPCs would fail to follow or find a path to their designated goals.

  • Fixed several issues with NPC being stuck in Online-Offline transition state,

• Enhanced A-Life NPCs' motivation to expand territory and actively attack enemies and mutants.

• Fixed issues that could result in fewer A-life NPCs encountered than intended.

• Further contextual actions improvement to ensure seamless transitions between Offline and Online states for NPCs engaged in these actions.

• The groups exploring the Zone are now more diverse regarding possible factions and group sizes.

• Fixed issue that while roaming over the Zone, Human NPCs didn't satisfy their communication needs and talks.

As for the rest of the update, there is a lot so buckle up.

Plus if all that was not enough, there are also over 500 fixes for the following:

• Foliage.

• Texture flickering.

• Bugs in navigation meshes.

• Collisions.

• Errors in object positioning and contextual actions.

• VFX-related fixes.

• Non-destructible objects.

• And more.
