Thank you both for the excellent replies! So, as I understand it, there wasn't really an official ZombieMod until around 2008? I've also tried to look up some threads and replies from before this date, and there are spare mentions of a kind of Zombie Mod from around 2006 as well. My only 'concern' is that CS1.6 was released in 2000, so in the 6 or 8 years during that time, no actual Zombie Mod plugin was ever made prior to Dias's mod?
