Back Track, a 1998 first-person shooter for the Game Boy Advance
The term "backtrack" was coined by American mathematician D. H. Lehmer in the 1950s.
The author/producer was Tod Davies, with whom Cox also collaborated on the scripts of Backtrack/Catchfire (Dennis Hopper, 1989) and Keith Moon was here (unproduced screenplay for Roger Daltrey, 2001).
