All character models have been completely replaced, including Doctor, Bartender, Sakharov, etc. If a character is wearing a helmet and/or glasses, a distinctive sound and effects will occur when a bullet hits these areas—glass shards or sparks will fly. The updated ragdoll physics are more complex, resulting in a greater variety of dead stalker falls. This was achieved by manipulating joint flexibility, damping, and the mass of each bone. Overall, more bones are used in the model physics. For example, if a stalker has a flask or pouch on their belt, it will be affected by physics. This adds realism and spectacle. The jaw will also move after death. Blood textures have been updated and enhanced. The UI has also been refreshed. Character, mission, and inventory icons have been changed. It is very easy to adapt. Hints for mod makers are provided in text format. Config files can be discarded if not needed. There are several models and textures created from scratch that were not previously presented anywhere. Ground models have been made for all costumes.
