An independent video game concept designer is in legal trouble for helping to virtually recreate the city's metro system for one of the most popular games in the world.
Montreal's public transit authority, the Societe de transport de Montreal (STM), threatened to sue Diego Liatis, 35, if he published his version of the popular game Counter Strike online.
Liatis was one of a team of independent developers who re-created Montreal's metro system as a background for the game, which involves teams of terrorists and counter-terrorists trying to kill each other.
Counter Strike is open source, meaning that just about anyone can make modifications to it.
Liatis said in an interview no one had developed a setting for the game based on a location in Canada and he wanted to be the first.
Unfortunately for Liatis, the city's transit authority didn't want its copyrighted metro network to be used for the game.
