For Man O' War: Corsair - Warhammer Naval Battles the huge Update 1.3.1 has been released for Linux on Steam.
It adds the Brettonian and Empire campaign to the game as well as a lot of other new features and improvements.
The full changelog:
Bretonnian and Empire campaigns!
For the outstanding Horror-game SOMA an Update including the "Safe Mode" has been released.
If you start a new game in "Safe Mode", Monsters won't actively hunt you and can't kill you anymore.
Sadly on existing save files, you can't turn on the "Safe Mode".
But: SOMA is in my opinion one of the best games available on Linux, and you have to play it - with or without "Safe Mode"!
