Left 4 Dead 2 Full Achievement List

Perhaps not realizing that the real achievement is the fun you have along the way, posters on Bethesda’s forums are in an uproar about not being credited for the Achievements they earned in the newly released Fallout 3 DLC, Broken Steel.

If you experience the same problem, take heart! Bethesda tells us [Via Joystiq], “The Xbox Live servers don’t seem to be fully synched yet with the additional Achievements. Microsoft is looking into it right now so that the Achievements folks have gotten will show up properly on Live (the game awards them, they just aren’t showing up right on Live for some reason). People won’t lose any Achievements.”

Patience, friends. Sounds like this will be resolved soon.

Xbox 360 Achievements are serious business. But obtaining that sweet Gamerscore nectar via nefarious means (like gamesave tampering) isn’t worth the effort, as shown by Microsoft’s sweeping smackdown on Gears of War 2 cheaters.

Xbox Live’s Larry “Major Nelson” Hryb informed the community today that the company has zeroed out the Gamerscores of Gears of War 2 cheaters, apparently caught with their hands in the Achievement cookie jar.“As you know, we are committed to keeping Xbox LIVE a safe and fair place to play for the more than 17 million active members,” Hryb writes on his official blog. “As part of our regular safety monitoring we have pinpointed a group of players who have unlocked specific Gears of War 2 Achievements through an unauthorized hack.”

Remember, kids, it doesn’t pay to cheat. I should know, because I definitely have never ever taken advantage of any glitch, particularly the Left 4 Dead “Jesus Room” glitch. You hear that, Microsoft? That’s the truth!

Gears of War 2 Achievement Hacking: Banning has begun… [Major Nelson]

Microsoft’s only on-the-record guidance on how Achievements are approved came more than two years ago, and the maximums it set then have been easily surpassed.

• A maximum of 1750 points and 80 Achievements for a full retail title. The Orange Box’s 99 achievements seem to be grandfathered in, although it’s an open question if they’ll be allowed to add more achievements should a Team Fortress 2 update come to Xbox 360.

•A quarterly maximum of 250 points and 10 Achievements for any additional DLC associated with that title. Additionally, these totals are cumulative, so a company could wait three quarters to do a large expansion with 30 achievements and 350 points, or parcel them out in smaller additions. X360A says its source explained the rule is meant “to stop companies from releasing a whole slew of content immediately after a game’s release to hit its 1750 max right away.”

The source had no answers if there were rules regarding rumors “no achievements for free content,” or requiring other peripherals or titles to unlock certain achievements. Still, this info, if legit, sheds a little light on how Microsoft tunes its policies with the goal of sustaining interest in a game.

I say if you get lucky, because one of the thirteen new achievements requires that the player “make love” twenty-five times, which for some of us represents many more times than in real life, depending on your definition of making love. For those of you who would rather stick to the path of purity, Lionhead has you covered. As long as you watch another hero making love twenty-five times you get the achievement as well. Pervert.

Luckily there are plenty of achievements on the list that don’t require doing the dirty, such as The Nutcracker, which simply requires you score twenty-five groin shots. Check out the full list below, containing several achievements that have nothing to do with the groin area whatsoever.

The Nutcracker 10
Score 25 groin shots, or see another Hero do so.

If a few questionable screengrabs and a handful of ESRB ratings weren’t evidence enough for you to believe in the XBLA-bound “Sega Vintage Collection Vol. 2,” we now present you with exhibit C — MyGamerCard recently dug up achievements for Altered Beast, Comix Zone and Shinobi, three of the titles belonging to the heretofore unannounced collection. Sadly, the other three titles which are rumored to accompany them, Sonic 3, GunStar Heroes and Phantasy Star II, are still unspoken for in the Cheevo department. We’ll let you know when we hear more!
