Full concept modification of S.T.A.L.K.E.R. Call of Pripyat that touches every game aspect including textures, sfx, music, weapons, AI, items, weather difficulty and much more.
In MISERY 2.0 the type of ammunition plays a bigger role.
Basically you must always pay attention to the type of round that you have chambered or packed away in your backpack.
Mutants will charge you almost unharmed if you spray them with small caliber armour piercing rounds as they tunnel right through them. But are stopped effectively with large caliber soft metal rounds that inflict severe damage in their unarmoured stature.
An armoured soldier is almost impossible to take down from afar if you land your hollow point rounds in his plated torso or other armoured areas. Use armour piercing rounds and they will cut through his bullet proof vest like darts through butter.
