Just as promised, GSC Game World's first post-launch update for S.T.A.L.K.E.R. 2: Heart of Chornobyl has landed. The patch is aiming to make the open-world adventure set in the Chornobyl Exclusion Zone a much more stable experience, with the studio touting the over 650 fixes being included in it for resolving "quest blockers, memory leaks, crashes, and minor bugs."
Aside from general optimizations and fixes for AI, audio, controls, characters, cutscenes, menus, and a whole lot of quests, the studio has made a massive number of tweaks to game balance too. This involves decreasing weapon and armor repair costs, better rewards for missions, easier rookie difficulty, reduced weight for some items, and HP reductions for a number of enemies that were called out for being bullet sponges.
