Valve has posted some interesting stats for Left 4 Dead 2's mutation modes. The team has been watching you closely as you work your way through the zombie hordes, and it turns out you like realism and gore in your L4D games: Realism Versus and Chainsaw Massacre have been the two most popular mutations by far, with Realism Versus (which was later turned into a permanent mode) grabbing 41 percent of the player base during its featured week and 22 percent of the playing time. The Chainsaw mode was the "most tried" of the mutations, with 52 percent of the player base revving it up, and 14 percent of player minutes spent playing it.

Outside of mutations, versus and the co-op campaign actually both nab about 40 percent of players every day. And while Valve doesn't mention any of the least-played mutations, it does give notice to the Infected-doubling Hard Eight mutation, which was only tried by 26 percent of players but still grabbed over 10 percent of that week's playing time. This week, it's a "Gib Fest," with everyone on the team getting M60s and unlimited ammo. That sounds like a hunting accident just waiting to happen.

We're normally pretty down on video game software piracy, especially when the games being plundered are totally DRM-free indie darlings. However, thanks to Machinarium's outrageously high piracy rate -- Amanita Design's Jakub Dvorsky estimates only 5 to 15 percent of players actually paid for the game -- the developer is holding a "Pirate Amnesty" sale for the point-and-click adventure game, temporarily marking its price down from $20 to $5.

So, because a ton of people obtained the game through illicit channels, we can grab it legitimately for 75 percent cheaper than usual? We're happy for the bargain, but that's setting an awfully bizarre precedent, guys.

The train of Square Enix titles continues to barrel through the PSOne Classics storefront on the Japanese PSN, as producer Shinji Hashimoto recently revealed the next PlayStation-era title bound for the platform. You can guess if you'd like, but considering how just about all of Squeenix's PSOne games are on the PSN -- in Japan, at least -- that might take a while. According to Siliconera's translation, the game in question is the original Chocobo's Mysterious Dungeon, an RPG you probably never played, assuming you weren't living in Japan in late 1997.

Hashimoto didn't mention any kind of time table for the game's arrival on the Japanese PSN, but we hear it's coming to the North American store sometime in Febtober, which is a made-up month, because it's never coming to the North American store.

Sega's Bayonetta will be released as a budget title in Japan on September 2 for PlayStation 3 and Xbox 360. As Andriasang (rightly) points out, the cover art for the budget release is demonically ugly, so it's a good thing that it can be reversed to reveal an awesomely artistic pink cover.

Checking with Sega about the excellent twitch-action title releasing at a budget price internationally, a company representative told us the publisher had nothing to announce at this time. Then again, Bayonetta currently retails for a budget-friendly $40, but you can certainly find it for less.

Privates, the latest opus from British indie devs Zombie Cow Studios, creators of such irreverent adventure games as Ben There, Dan That and Time Gentlemen, Please is now available to download for free through the television station which commissioned the game, Channel 4. We've been playing it for a half hour or so, and can confidently say it's the best comedic, educational run-and-gun shooter set inside of a human vagina that we've ever played.

In all honesty, Privates is actually a fun little game with clever touches to make it a legitimate tool for teaching teens about sex -- for instance, you have to scan enemies (HPV, herpes, sperm, etc.) to learn more about them, informing you and the rest of your squad about their real-life symptoms and in-game weaknesses. It's fun, enlightening, chock-full of humorous dialogue, and, yes, it also contains a level titled "Campaign in the Arse."

Remember that famous scene in the The Godfather where Michael tells Fredo to never take sides against the family? Well, in the world of Mafia 2 -- set in post-WWII America -- that movie wasn't filmed yet, so PS3-exclusive DLC protagonist, Jimmy, never learned that lesson. Feel free to see what we mean in our gallery of fresh screens below.

The Betrayal of Jimmy DLC will be free to all who pick up Mafia 2 for the PS3 new (via an included voucher) and available for download through PSN for $9.99 when the game launches on August 24.
