Note that many of these missions can be completed in a different order than the one presented below.You may have two or three story missions available at a time and can complete any one before moving to the next (although you will eventually complete them all).With a huge Liberty City to explore, impressive detail, sharp writing, compelling characters, and a ton of side missions and activities to complete, Grand Theft Auto IV is not only the best GTA game ever, it’s one of the best games ever period.
Also Michelle/Karen I believe her chararcter simply an exceptional actor who has to play different roles.
Judging from the fact that she worked for the United Liberty Paper Co, and joined the IAA later on, her government background proves this.
We were all talking about it from start to finish of the entire Heist.
I actually wouldn't mind seeing Karen as a protagonist.
She's very mysterious and her back story could be very interesting.I could see a story starting just after the events of GTA IV.
