Left 4 Dead 2 goes free today, stops being free on Monday

Free to play "weekends" seem to be getting bigger and bigger, but you don't hear me complaining.

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 weathersome 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.
