A database vulnerability at Valve has resulted in the leak of a large list of  developers working on various Valve projects, most notably Half-Life 3 and Left 4 Dead 3.

Notable team members for Half-Life 3 include engine developer Alex Vlachos and Portal 2 level designer Adam Foster, and for Left 4 Dead 3 there’s creative director of Splinter Cell and Far Cry 2 Clint Hocking. Valve has several heavy hitters working on both games, including Portal writer Erik Wolpaw, veteran Valve musician Kelly Bailey, and Counter-Strike co-creator Jess Cliffe.

A healthy part of the list is also devoted to people working on Source 2, the sequel to the Source engine that runs many Valve games, third-party games, and game fan mods.
