The King of the Hill

As Murray clears the first hill, an enemy will come around the first building, followed by another on the other side.

As Murray crosses the bridge, shoot the enemy that pops out of the green structure ahead, then hit the rocket at the end of the stretch.

As Murray hits the trees after crossing the makeshift bridge, shoot the enemy that gives chase, and then the one who emerges from the trees shortly after.

When you approach the elevator to the next level, be prepared for a guard coming around the building and another emerging beside the lift.

At the top of the second level, defeat the single enemy waiting to ambush Murray.

Murray will go up another elevator; an enemy lurks just ahead.

As you pass over the green structure, shoot the monkey emerging from the snow tunnel.

Murray will run up a series of elevators to the next level.

At the top, defeat Andre and shoot the rocket beside him.

Once Murray crosses this latest addition to his course, quickly shoot General Tso as he appears on an elevator.

As Murray enters the next building, defeat the two monkeys that attempt a pincer attack.

When Murray makes his run for the key, a siren will sound, causing gorillas to appear randomly around the building.

After you shoot the tenth gorilla, Murray can grab the key.
