The folks over at GOG.com aren't just having your normal holiday sale. That's not their style (or how they roll to use the youngster vernacular). Instead they are giving away the Tex Murphy pack which includes Martian Memorandum
and Mean Streets
for free until December 24th. All you need to is go here
and you can download 27MB of gaming goodness directly to your hard drive.
Of course you might also want to pick up a few other cool titles while you are there (Freespace 2 jumps
to mind). Or you can just download it and spend your holidays knee deep in Martian noir (which might be more fun that spending time with your family).
