From the update:
Fantasy Flight Games is pleased to invite you to take part in the open beta test for Only War, the upcoming Warhammer 40,000 roleplaying game!
Announced in April, Only War places each player in the role of an Imperial Guardsman, one of the countless billions of hardened conscripts constantly fighting on myriad fronts at the whim of the Adeptus Terra. Your squad might be responsible for guiding an important dignitary through a perilous warzone, or instructed to infiltrate a besieged fort to deliver important intelligence. With missions as varied as the galaxy’s innumerable warfronts, you and your squadmates must often rely on nothing but your own grim determination and your faith in each other.
Available for download through drivethrurpg.com and rpgnow.com, the Only War beta provides an abridged, electronic version of the upcoming core rulebook. This 265-page pdf document retains the core experience of Only War, but excludes certain thematic content that will be present in the final game. As part of the beta test, you’ll provide valuable reconnaissance for the war effort as you help us to craft the best possible product.
