STALKER 2: Heart of Chornobyl launched with several bugs and issues, which GSC Game World, after celebrating the million units sold milestone, promised to resolve.

How Did You Fix "A-Life"?
Duct-tape. The AI director in STALKER 2 is actually very complex internally, however its function is gimped because of severe bugs compounding each other. I troubleshooted the present bugs to the extent of my ability and duct-taped a solution to coax the A-Life system into working around its own field of anomalies, so to speak.

What's The Catch?
Performance. This mod
