Ever wonder why an axe to the forehead didn't kill that stalker? Not to worry, knives are not toys modifies the damage to all melee weapons to a more realistic approach.
All knives do about twice as much damage than before making stealth mission possible with a one hit kill to the back of the skull with a good knife. I recommend using this mod for a more immersive (and possible) stealth experience in stalker.
This mod changes one file [m_knife.ltx] and is not compatible with anything that changes said file.
