Earlier this year I finally managed to track down Kevin MacFarland, author of the Atari ST BBS door game "Assassin." Thought you guys might enjoy my interview with him. Back then he went by the handle "C Monster."
I also wrote up a blog post remembering Assassin. If anyone else remembers the game, I encourage you to leave a comment on the blog!
(And, as I mention in the blog, you can still play Assassin today on Dark Force, The Grove, and Starfleet HQ BBSes.)
