Valve is working two angles to get Left 4 Dead 2 on Australian consoles and PCs, following the Aussie ratings board's refusal to classify the zombie shooter. One version of L4D2 making its way through the OFLC is an "Australia specific" (i.e. edited) take on the game, while the other is the gore-lovin' original, which Valve currently has on appeal.
Gamespot spoke with Valve's Gabe Newell, who explained that the next step for the unedited version won't occur until October 22, which means the timing gets tight in terms of manufacturing and other hurdles before a November 17 launch. Valve project manager Erik Johnson finds the OFLC's issues with the sequel to be "inconsistent" because of Left 4 Dead's unedited release in the region. We wish Valve (and the gamers of Australia) all the best in working out those Michael Atkinson issues.
