Rambo is in store for a tough gun fight in the Rambo Robot Mayhem first person shooter. In this FPS game you not only have to battle the enemy soldiers who are trying to shoot you but you will also have to destroy the boss which is a massive robot. At the beginning of the levels you will be told how many enemies you need to shoot so you can move on to another level. Kill them all and try to survive. Your gun will auto fire once you start shooting but keep an eye on how many bullets you have left so you can reload your gun before you get shot.
