Overview

  • Patch 1.5 overhauls the A-Life system by simulating NPC behaviors beyond the player’s view, reducing pop-in and enhancing immersion.
  • The Zone Kit modding tool is available on the Epic Games Store and lets players craft custom animations, weapons and mechanics for sharing on Steam Workshop or Mod.io.
  • While early system requirements cited roughly 700 GB of storage, users report that the toolkit downloads at around 471 GB and expands to about 659 GB on disk.
  • GSC Game World describes Zone Kit as Phase 1 and intends to refine its modding tools through ongoing collaboration with mod makers.
  • The patch also delivers numerous bug fixes, performance tweaks and improved ultra-wide monitor support to enhance stability.
