Good Morning Zombies

After a successful mission against the enemy of the state, you are now headed to your home when the helicopter to which you are on got shot.  It crash landed on the jungle.  You thought that nothing bad could top that, but you are wrong.  There are zombies all around you and they want to eat you.  You grab your gun and started firing every one of them. Kill all the zombies that you see!  You will earn money based on the zombies that you had killed.  You can use the money to upgrade your weapon, buy a new weapon or to use it in anything that would help you.
