On Friday we thought Crysis 2 was going to be the biggest game to fall to piracy possibly in 2011. But we were wrong, and only a couple of days later Killzone 3 also appears to have been leaked.While Crysis 2 is a mere 9.22GB download, Killzone 3 almost fills a Blu-ray disc and is a 41.4GB download. It’s the European version of the game and includes 3D output. If you don’t want that, then a second torrent is available which is half the size without it.The only good news for Sony and developer Guerrilla Games is that you need a hacked PS3 to play the game. While that’s becoming more common, it’s only going to be a fraction of a percentage of consoles out there at the moment. Lost sales thrugh this leak will be minimal if any are lost at all. Anyone who has a hacked PS3 wasn’t likely to buy the game anyway unless they were planning on supporting the developer with a purchase.The official version of Killzone 3 gets a release on February 22. A single-player demo will be available tomorrow on PSN.Read more at Eurogamer.netMatthew’s OpinionAgain, there’s no information about who leaked the game, but this is a much larger game to steal and must have taken a long time to download, or at the very least upload from a disc copy.With only two weeks until the game is officially released this could have been terrible for sales, but the fact you need a hacked PS3 to play it limits the damage to a large extent. The worst we will get is videos appearing of gameplay and a few reviews (good and bad depending on the game).As with EA and Crytek, I expect Sony and Guerrilla will track down whoever leaked the game and take action. You only have to look at what Sony is doing to Geohot at the moment to know as a company it doesn’t hold back when it comes to piracy and hacking on the PS3.
