So, Gog.com's twitter just posted the game was free to claim for 48hrs but the store page says newp, still 9.99.
anyone know if just missed the sale or something?

Yep, you were some two hours late

The 48 hours started Saturday morning. =)

Same problem here.
Got mail on 12/12 at 9:39 am, checked the web few hours later and nothing, checked on 13 in case and nothing.
Since mail says "For more FREE games, check back on Monday, December 14, 10:59 AM GMT" i tried again said day and still nothing.
Today i tried again to see if it would finally show up and still nothing.

Seeing as theres posts of people asking same question i assume must have been some problem with the web or country restricted maybe, since between i got mail and monday 14 there werent even 8 hours between check and check cause i really wanted it.

Too bad some of us couldnt get to get it, hope for next time theres no problems, or if it was a country restriction, just dont send the mail to us who aren't included ;(

Everyone was and is included, you must have recieved your mail late. Here is a link to the latest freebie http://www.gog.com/promo/weekly_staff_pick_team17_anniversary_sale_141215
There is still, as of now, over 28h time to claim that one.

It was a time limited offer which has since long lapsed, over a month ago. Better luck next time
