I've claimed the DLC, it appears in the list in my library, but as "not installed" and I can't seem to install it... (and yet it seems I can use it, oh well...)

If you have retribution installed then the game should update, wait a bit or try launching the game.

I still think its going to be a long while more before anything appears

Animator post for 6-12 months on Relic's website, for promotional and marketing videos. Maybe there will be something by the end of the year or early '17, but we'll see.

Either way it's pretty much confirmed, rooting through the job profiles, that Relic are working on an unannounced title

Ah well, i'm still playing Soulstorm to this day, which i personally consider it to be the best 40k game ever made, so i'm not too impatient.

Maybe one day, maybe.

I upgraded to windows 10 and soulstorm never worked again after that. RIP dark eldar :[

Oh man, that sucks. I actually use windows 10 too but my Soulstorm thankfully works. (steam version)

PC can be a capricious beast sometimes sadly.

I fear what will Relic under Sega do with title.
