Hand of Fate has been updated, includes the Murder at Sea free content.

Changelog:

Patch 1.2.7 (06.07.2015):

Our latest update, Murder At Sea, adds a whole new questline to Hand of Fate.

To begin your new adventure, visit the Land Locked Lubber (which will be in your deck after the update) and speak to the bartender there.

DEFCON

Changes for 06.07.2015:

We have added a new Windows build of DEFCON that offers better offline functionality.


I doubt it though.

The key word being "better".

Yes. They are.

Good :)

OMG that's really suspicious. The GOG version was lacking content for a while and it wasn't part of the summer sale.

NOTE! CHANGED DEFCON, file_size: 70 MB ***TO*** 72 MB





NOTE! CHANGED Gratuitous Space Battles 2, file_size: 380 MB ***TO*** 382 MB

[I don't own this game, so MaGog will not be able to report any downloadable file changes]

i see updated with 2 megabyte more of extra delicious drm content :)

Nah, DRM, like smoking, was just making the game a bit slimmer. :P
