For me, it was Black Squad
Only the real ones know
so even tho i'm not that old but i don't find anyone that played
CS 1.3 and 1.5 i used to go after school with my friends and play it together, but i've never seen anyone who played them on the internet
every cs player started from 1.6 for some reason
