On game #13, end the game with 90 points scored or less (score no points during the round, and have 3 or less missiles left in your base) and the letters RF (for Rob Fulop) will appear in the right-most city.
Two different versions exist. One version doesn't contain Rob Fulop's initials, the other does.
Great game one 2600 version that was close to original 400/800 even better shame in did'nt have end sequence on 2600 might have been hard work in 1981 ...

The NBC series "Chuck" from the team behind "The O.C." did a full episode honoring this great game. It's Season 2 Episode 5 "Chuck vs Tom Sawyer". Quite funny. And the best: In this episode Atari is still alive and kicking. Also funny is the Billy Mitchell look alike in the beginning.
Happy watching.
