    This is the fourth mission given to you by Ray. You unlock his missions whilst completing missions for Packie, so if you have the 'Full Exploration' achievement you will have these unlocked.

    The first three missions are quite easy, but this one is rather tricky. Make sure you have a gun, it's a good idea to get some body armor too.

    Begin by shooting all the guys on the top level of the museum. With a bit of practice in free aim with a pistol, headshots (1-hit kills) are easily achieveable. Before heading down the stairs, grab the health on the wall next to the opening where the stairs are.

    Now clear out the guys on the bottom floor, there's some armor on the counter to the left as you come down the stairs.
    Go through the door, kill a few more people and quickly grab a car before Issac's guys shoot you.

    Escape by driving quickly to the other end of the park and this achievement is yours.

    magnusjsampsonWhen you arrive at the museum, block the alley exit across the road to prevent isaac's guys from driving out when you later exit the museum. When you are exiting the museum, make sure you blow up the 3 cars parked up front. Run across the road and finish off isaac's guys trapped in the alleyway and the last car driving around

    Christian DoeYou can shoot most of the guys on the bottom floor from above. You'll get better protection, and accessing the lower level and the exit will be easier later on.

    Skelebone XVII recommend shooting up Isaac's crew that are outside before getting in a car. There are a few stragglers that are outside the building and some that follow you from inside, and it is best to hit these while on foot. A couple will come at you in cars, and you should try to shoot the driver or wait for someone to lean out the window to draw a target. If you get in one of the waiting cars they will chase you down while shooting at you from a car that goes just as fast as the car you are in, and they are more difficult to deal with this way.

    Since you're firing in the open in the park, you will draw some heat, but depending on your speed and accuracy, you should be able to only draw two wanted stars, easy to evade after Isaac's men are all dead.

    Moody CogsworthAs I got in the car to escape, I pressed the x button and dropped a grenade. That seems to sort the men from the boys ..
