Yesterday Stalker 2 developer GSC Game World dropped a massive 12GB patch that totalled 650 fixes. Well the studio didn't waste any time as today they have released patch 1.0.2 to fix a variety of mission based bugs.
Stalker 2's 1.0.2 patch is much smaller than yesterday's 1.0.1 with only a handful of new fixes, 6 to be exact. All 6 are related to campaign missions. Additional there is 1 fix for the PC version of the game related to an error. It should be noted that patch 1.0.2 is currently only live for PC, with the Xbox version set to receive the patch "soon".
