If you haven't checked in on Dawn of War II lately, now might be a good time. Dawn of War II - Retribution expands today with the addition of the Ulthwé Pack, which introduces Craftworld Ulthwé along with nine unique models for major multiplayer units, plus a number of other customization features.
The new content is available for $7.49 USD, and if you're not exactly sure about dropping that kind of money, check the new screenshots for a preview of the new Eldar skins.
DLC aside, the 3.16.1 update also introduced a number of fixes, which can be viewed on the official forums. A few issues have already been discovered, and Relic is working on the 3.16.2 Hotfix.
