Thereís regional locks on it, which means basically that it needs to be midnight tonight in your region before you can play Mafia City.

 For the US, this is midnight eastern time. Take an hour off for each timezone you are west of there - nice and early 9pm start for the California/Seattle crowd.

 In the EU, itís midnight British. Thatís 1am if youíre on CEST, 2am if youíre a little further East.

Elsewhere, youíre best off checking the Steam page yourself. Just remember that Steamís times are a little dodgy - if it says approx 10 hours, thatís 10 hours plus some amount of minutes. Gangster games, A midnight release will display as approximate two hours at 9:01pm because it is two hours and 59 minutes.
