You'll need GTA UNITED for this Mission.
Hey, I decided to make a Story about the Russian Mafia cuz I'm a Fan of the Russian Mafia and cuz I'm half Russian.
This is only a Trailer with Cutscenes not a Mission.

However the Story is about a Russian Mafiosi called Alexander. (Yes I choose it because it's my name :D)He's a important Soldier for the Petrenko Family. To make the Petrenko Family the strongest Mafia in Liberty City and Vice City he has to defeat the Picocelli Family and the Antilotti Family. His best Friends Vitja, Seryoga and Roman will help him.

PS: The Missions will be finished in 2-3 Days.
I don't know why, but in the whole Mission stays Missiondesign by Lil Alex. It should disappear after 5 seconds but it don't. But well, I think it's not a big problem.
