First, the Good: The suddenly puritanical Australian government -- by way of The Office of Film and Literature Classification -- has seen fit to grant the previously unclassified Left 4 Dead 2 an MA 15+ rating, paving the way for millions of impressionable minds to be programmed into zombie-killing machines.
Next, the Bad: The version of Left 4 Dead 2 that the OFLC approved was an "edited version" that "no longer contains depictions of decapitation, dismemberment, wound detail or piles of dead bodies lying about the environment." In other words, it's nothing like the real zombie apocalypse. And when the inevitable human-vs-zombie war reaches Australia's isolated shores, her people will be ill prepared for what they encounter. "Gross, these zombie corpses don't disappear when you kill them! And, what's this? Blood?"
Valve and publisher EA are still hoping to launch an unmodified version, pending the October 22 review by the OFLC board.
Lastly, the Ugly: 1UP noticed a "special modifier" in its Scavenge Mode demo last night: "Realism mode." Valve's Doug Lombardi explained that it was for the serious player: "Take Portal for example: We had our best internal players who could blow through that game in about 30 minutes, but within weeks of launching it we had people on YouTube beating [the testers'] times by 10 minutes or more. Realism is for those players." In other words, it's training for the real zombie apocalypse. If our imagination is any indication, expect Realism mode to feature plenty of realistic pants crapping.
