Semper Fi
For an opening level, Semper Fi has a few sections that can give you trouble. After you escape and begin to work your way through the beach huts, keep your eye out for a Marine going hand-to-hand with a fiery Japanese soldier save him and you unlock an achievement. The next tricky part is the ambush in the jungle, which you can beat by taking cover behind the burnt hut. Finally, the end requires you to plant explosives, then escape on the boat. Dont mess around here trying to kill all the enemies just sprint for the objective.
