Sometimes I'm the shark; sometimes I'm the swimmer.
The description says the designer had a long article in The Space Gamer #23. I don't remember if it had solitaire rules but I can check.Another BGG thread on this issue reports on the article as follows:
"Invasion of the Air Eaters Designer's Introduction & Multi-player Scenario by Keith Gross is an excellent addition to the original game. If you like the game, this is probably the best article ever done on it. (Wait, I know what you're thinking -- this is the only article ever done on it. Well, it's still a good article). A good look at the thought process behind the game and a lot of chrome added to good effect."
