Mercenaries 2: World in Flames

Hello, Hooray - You acquired the PMC.

Just take the PMC from the enemy, its a normal mission early on the game

To get this cheevo all you have to do is follow the first couple missions in the game, once in the mansion a tank with burst through the wall and you will have to kill 10 more people in the room. The easiest way to do this is to hijack the tank (you also get the Ride the Dragon - 10G for hijacking it). then proceed to blow up the 10 people, the mission will end and you will get, probably the easiest 50G there is.
Good Luck!

This is one of the earliest missions in the game and you have to kill soldiers out side of the mansion then you get get it as a base of operations
