Free to play "weekends" seem to be getting bigger and bigger, but you don't hear me complaining. As a relaxing aside to the spooky Halloween weather some of us will be experiencing, Valve's calming co-op zombie apocalypse shooter, Left 4 Dead 2, will be entirely free from today through to Monday. The expiry date is moot, however, as we'll all have been eaten by ghosts by then.
To tempt Left 4 Dead veterans back into the fray, Valve have added a new achievement called "Good Guy Nick" which will be awarded to those who help new players to survive a campaign. "Who is a free weekend player? You're going to have to talk to each other to find out." Talking to people? On the INTERNET? 'Tis Halloween indeed.
Left 4 Dead 2 will go free at some point today according to the latest post on the Left 4 Dead 2 blog .
