During the GOG Winter Sale they have another game giveaway and so you can grab the classic I Have No Mouth And I Must Scream for free right now. The giveaway lasts until December 25th at 2 PM UTC.

This is part of their Throwback Thursday series, for which they have a dedicated list of other retro delights you might want to take a look at.

As a reminder of some of the big lists GOG have for their Winter Sale:

• Local gift guides - region-based recommendations from their Community Managers
• Warm and cozy - delightful adventures to brighten any day
• Roach's recommendations - Geralt's trusty horse's own selection apparently
• Timeless Classics - come back to the roots with a page full of good old games
• Best Sellers - those that speak for themselves
• New arrivals - need I say more?
• GOG Exclusives

If you've picked up anything good in the GOG sale, do give over your recommendations in the comments. There's been a number of new deals added since we originally wrote about it for the first giveaway. GOG are also doing Flash Sales every 24 hours on their homepage.
