HK-51 — you talked about how he’s coming with new missions, etc. and you’re basically unlocking him?

HK-51 is actually part of the Legacy system. He is a very hard companion to get, and there is an incredible amount of work that you’ll have to do. I will say right now that if you do not have people on both sides of the war, you probably need to go roll somebody on the other side.
