Have you checked out the sprues
? If this is legit then there's nothing unique about these models aside from what transfer you apply to the shoulder.
The game itself is almost inconsequential to my desire for less expensive, plastic, and more accessible Heresy-era models without resorting to Chinese knockoff manufacturers. That being said, it could be cool if it is what it's rumoured to be. I just hope it's not "players 1+" like the Assassins game was. I used to love goading my older sister through sheer attrition of will into games of Space Hulk when 2nd edition came out.
Fuckin' classic right there.
