If anyone wants to "speculate" on Bloodshot or A&A, the issue to get for Bloodshot is Rai 0, his first full appearance. Eternal Warrior 4 is his first appearance as a cameo on the last page (it came out a couple weeks befor Rai 0). For Archer & Armstrong, the gold logo edition of issue 0 is the book to get, then maybe the regular zero issue. It is the actual first issue, and first appearances of Archer and Armstrong.
Bloodshot 1 wasn't printed quite at Turok 1 levels, but here are plenty out there.
