I was reading about it in wikipedia. It said, "Radiation poisoning can be cured with a substantial amount of vodka is consumed." LOLWTF When a nuclear war happens, always bring vodka with you.
thats because in stalker vodka is 100x cheaper and 100x more common then anti rad drugs but it makes you drunk..
fun fact: you can drink over 100 bottles of vodka and only get tipsy
on topic: STALKER! YUS! a bit unbalanced. Don't get Clear Sky though, that one is horrible.
