Miss Him, Miss Him, Miss Him (1990)

From the back of the book:

Alarms flash and klaxons sounds as every available Time Corps agent rushes to the field. Somehow a full-scale nuclear war has broken out in 1970 and the disruptive Time Wave spawned by that fiery destruction will wipe out the Time Corps in a matter of days unless the cause behind the change in History is found and fixed.

Even new recruits like yourself are being rushed through training to aid the reconnaissance effort. After a quick drill on Time Corps procedure, you're sent to a Time almost 20 years after the bombs stopped falling to find out what happened from the survivors.

So you go back, masking your uncertainty as to what to do, to try to find the key. But a lot has changed ... from geography, politics and economics to music, shopping, and computers. What is cause and what is effect?

"Miss Him, Miss Him, Miss Him" is a 40-page training module and adventure for use with the Timemaster Role-Playing Game, with historical background, characters, and exhibits for hours of play.
