No, not familar with those titles, nor Ted McKeever, well not to any great degree. Ill do a bit o' googling and check them out.
Got into Dark Horse in a big way in the very late 80's because of their Aliens and Predator stuff. Those early stories are brilliant. Love Chris Warners art on Predator and Blackcross.
That got me checking out other DH stuff which lead to Concrete, Martha Washington, JB's Nextmen etc.
Think DH got it so right in those early years.
