Full concept MODIFICATION of S.T.A.L.K.E.R. Call of Pripyat that touches every game aspect including textures, sfx, music, weapons, A.I., items, weather, mutants, difficulty and much more!
Meat can be cut from some mutants if they not seem to suffer too much from various injuries. This provides a cheap way of surviving for some stalkers. For others it is all a matter of saving their money for other equipment.
Eating cooked mutant parts will unbalance your health but your only alternative is the more expensive imported consumables.
Some stalkers eat mutants as a symbol of human superiority and masculine showoff. Some stalkers focus on health and spend their roubles on the imported goods. So having a few imported cans of food on you does not necessarily generate a symbol of wealth among others.
