this mission is hard

To kill Dimitry?

I haven't got this far yet, unless you mean the mission 'Russian Revolution' where you and Little Jacob tear through the warehouse, defeating the men.

You have to take your time, killing them off, man by man, and slowly advancing. There is a first aid pack on the right hand side, you can use in the small room. When the police arrive, you should only have to take out a few more numptys, and then move to the door. Press RB, so you lean against it, and lean out, only to shoot the police closest to the closest car,otherwisethis will raise your wanted level, and make it harder.

Once you kill the two cops, get in the car, and drive off, losing your wanted level, before taking Jacob back to the Cafe.

If this isn't the level, please state the mission you are on. You can tell, by pressing start, and going on the brief, where it should tell you, at the top.

How far into the game are you? Cause I'm on the 2nd island and I havent killed dimitri yet.

He is almost in the end of the game

There is an easier way to kill dimitri but depends on the decision you make if you work with dimitri or kill dimitri

I recomend working with dimitri but if you do that roman get killed on his wedding

Get better at your aiming skills.
