Fire Chimera — rare mutant Zone may exist in a single copy. From the usual Chimera differs much increased resistance to fire anomalies and fire in General, but also accelerated recovery and more survivability. If you fill up the thing, then you can immediately become a legend in the Stalker community.
Skin is made qualitatively, but there are some bugs with the gait. You can use this skin in any of its purposes.
Have a nice game!
