There's a new achievement available for Left 4 Dead 2 veterans who help new players this weekend.
Left 4 Dead 2 goes free to play today in honor of the spooky season, and new players are encouraged to start downloading now. This offer will only last until Monday 10AM PDT, so if you know someone who might be interested, get them in pronto!
If you're a veteran, there's an achievement in it for you: Good Guy Nick, which will be awarded to old hands who help the new players survive a campaign. How will you know who's new and who's not? Good question, but Valve has an answer: "talk to each other to find out." Radical thinking indeed, but you could always persuade a buddy who hasn't played before to join your game.
For more information, check out the Left 4 Dead 2 blog. The blog post includes a link to a download of the game, so new players interested in a free weekend should head over there too.
