While it isn’t as big news as everyone seems to be making it out to me (After all, I assume most online gamers would have already picked the game up), the team behind Left 4 Dead 2 have confirmed via their official blog that until 10AM PST on the 26th December 2013, you will be able to pick up the game for free – and can continue using it for the life of your account.
All current players on the other hand can earn the achievement “Ghost of Christmas Present” by helping a free holiday player survive a campaign.
