The Shasvastii background was already in Third Offensive. Bostria stated that the release was delayed in short term
Oi, so I definitely need to find some time to read Third Offensive, before Daedalus' Fall arrives! I expected the Shasvastii fluff to arrive with the remake and that Daedalus' Fall will be the corresponding book. On the other hand I exptected the Tunguska fluuf to be in Third Offensive... Seems like the release of the Tunguska and Shasvastii fluff and their respecitve sectorials are totally mixed up. :)
