Looks fairly interesting. Are the soace wolves actual space hulk terminators? Or like a squad of scouts, so they're more in line with the other forces. And can we can the whole squad of that faction, or just of the characters in that squad?

The Space Wolves would be a small boarding party, and if any Imperial forces are they would act as escorts. Astartes will be outnumbered in this for balance. This story is sort of a mixture of Rogue Trader and Space Hulk, so I would like to limit each player's crew, squads, or party to about the size of a Kill Team plus one or two scouting vehicles. For Space Marines I may just make that a squad of terminators or marines without vehicles in a boarding party.

(Because balance, your characters would be about as tough as say an Imperial Naval force with a chimera brought aboard.)
