Valve Leaked Left 4 Dead 2 Trailer After ESRB Block

Chet Faliszek, writer on Left 4 Dead 2, stated that Valve leaked the game's 2009 cinematic trailer themselves. The ESRB would not approve an official release, so the team posted it unofficially. Faliszek noted the strategy meant Valve could not get in trouble for the content. Recent articles from GamesRadar+ and PC Gamer quote his comments on the decision made at the time. The trailer appeared ahead of the game's November 2009 launch.
