The much-anticipated STALKER 2: Heart of Chornobyl has been stirring up excitement within the gaming community, particularly among long-time fans of the franchise. In a recent interview with GSC Game World’s technical producer, Yevhenii Kulyk, new insights have emerged about the enhancements made to Unreal Engine 5 (UE5) to accommodate the unique demands of STALKER 2, particularly its famed A-Life system and the potential for modding. The interview, conducted by RadioTimes at GSC Game World’s Prague office, shed light on how the team at GSC is going above and beyond to deliver an immersive experience that stays true to its roots while leveraging modern technology.
A-Life System: Breathing Life into the Exclusion Zone
One of the most exciting revelations from the interview is that A-Life, a key feature that drove the popularity of the original STALKER series, is fully integrated into STALKER 2. For those unfamiliar, A-Life is an intricate AI system that simulates a dynamic, living world, allowing various in-game factions, NPCs, and creatures to interact with each other, even when the player is not present. According to Kulyk, this feature will be enhanced in STALKER 2, maintaining constant activity in the game world.
He explained how this would work in the new installment: “First of all, they have [offline mode]. [Constantly] some events are happening in the back end. So you may notice that during your gameplay… maybe some firefights or mutant encounters that were attacked by NPCs or vice versa.” This essentially means that the Exclusion Zone will feel more alive than ever before, with players discovering the aftermath of battles and events as they explore the landscape.
Just like in the older games, NPCs and monsters will have their own designated zones but can roam freely in search of players or each other. This ensures that there is “constantly life in front of the player, and, of course, [where they aren’t looking],” providing an immersive and unpredictable gameplay experience.
Unreal Engine 5: Customized for STALKER 2
To bring STALKER 2’s sci-fi depiction of the Chornobyl Exclusion Zone to life, GSC Game World had to significantly rework Unreal Engine 5. Kulyk referred to the game’s custom build of UE5 as “5.1 GSC,” emphasizing the extent of the changes made. According to him, the development team “had to adapt and [rewrite] and upgrade some tools that were provided by… the basic Unreal Engine to fit our needs to create [this] world.”
These customizations were crucial to preserving the eerie, atmospheric environments and complex AI interactions that STALKER fans have come to expect. Transplanting the unique STALKER vibe into Unreal 5 was no small feat, but Kulyk’s confidence in their adaptations suggests that GSC is on the right path.
Modding Support: A Comprehensive Toolset for Creators
Another major highlight from the interview was the confirmation that modding will not only be supported but actively encouraged. STALKER 2 is poised to provide a robust set of modding tools from the early stages of its release, allowing creators to dive deep into the game’s systems and design. “We’re creating and preparing the very big toolkit that will provide the mod makers with basically all necessary tools to create mods from, like the smallest one to, like, big, total conversions,” Kulyk shared.
This is a promising development, particularly for fans who enjoyed modding previous STALKER titles. Mods like Anomaly and Call of Chornobyl are fan favorites that expanded the A-Life system’s complexity, and the new toolkit promises to enable modders to create similarly ambitious content. Whether players are looking for minor tweaks or total overhauls, GSC’s mod kit will open the door to a thriving modding community.
Conclusion: A Hopeful Future for STALKER 2
For long-time fans of the STALKER franchise, the details surrounding the A-Life system and modding tools are encouraging signs that STALKER 2: Heart of Chornobyl is on track to deliver the immersive, unpredictable, and engaging experience they’ve been waiting for. With a customized version of Unreal Engine 5, an enhanced A-Life system, and a comprehensive modding toolkit, GSC Game World is laying the foundation for what could be the most ambitious STALKER game to date.
Now, it’s just a matter of waiting to see how well these innovations will come together. If GSC delivers on its promises, STALKER 2 could very well become a modern classic, combining the best of the old with the innovations of the new. Fans of the franchise can only hope that the wait will be worth it.
