An early - and playable - prototype for Left 4 Dead has reportedly leaked online.
Described by the mod developer as "a historical dev map seen for the first time outside of Valve's office", the "Zombie City" mod for Counter-Strike: Source by WolfCl0ck was quietly uploaded to Gamebanana on Friday as part of a larger leak of Counter-Strike maps.
"Zombie_City is a map created by Valve (or possibly Turtle Rock Studios) that was a part of the map sources folder that released today," the mod description page teases (thanks, GamesRadar+). "It is likely the starting point of Left 4 Dead, and for those of you who have heard the name 'Terror-Strike' before, you will love to get the chance to play this prototype level.
