...there was this kickass game called Zero Tolerance.

It was clearly the best of all first person shooters for good
old Sega Genesis. Its developer, Technopop, later had some
money problems and sadly had to shut doors.
More recently, Eidos announced a game named
Zero Tolerance: City Under Fire. Randel Reiss, once
president of Technopop, and still the retainer of its assets,
promptly sued them. So Eidos had to rename their game
Urban Chaos: Riot Response.
Reiss also announced that the real Zero Tolerance
will get an updated PSP version.
