Rambo is left to die in the zombie infested jungle as an army helicopter rescued the rest of his team from misery. Help the deserted hero to survive and protect his base from hordes of bloodthirsty undeads using a variety of weapons. It's absolutely necessary to stop the attackers before they can break through the barrier or he will die, so use all money to purchase tons of upgrades between the waves. Good luck.
