Keep playing in the same room until level 4 or 5. after you get 600 points or more buy the M1 Carbine, and use that for awhile. I usually shot them 3-4 times then finish them with a melee. When you first start run around until you see zombies now shooting them is good but if you shoot them a little bit then melee them you will get more points for killing them.

I have noticed others have posted their strategies but I have one of my own and since it won't be too long to describe I will submit it as a hint. *NOTE There may be more Ptrs, but I haven't found any I recommend you keep the machine gun you start with. use a combination of these weapons to blow the enemy away. The building on the right has a panzersrehk on a shelf and a PTRS leaning against the wall. Continue onwards until you see the part with two buildings, with ladders go up the one on the left to find an FG42, on the floor, and a Panzershrek on the shelf. The next FG42, and panzershrek are after you destroy the second gun advance up the stairs the Panzershrek is leaning against the wall and the Fg42 is up the other stairs, laying on the floor, assuming the man is dead. After destroying the first crew there is a destroyed tank, leaning on the tank there is a panzershrek, it only has one ammo, so either use it on infantry or the next gun. Continue on the battlefield to where you destroy the flaks or antitank guns, on the way you will see molotov cocktails.

Now pick it up and continue advancing, until you get inside the library or whatever it is, go to the area where the bad guys are and you will see a hallway, go down the hallway and there will be a room with an FG42, and grenades. In the begining of the game you are told to go to the left of the area, near where you go, but BEFORE you see the building where your men are running inside, and heading towards the battle there is two boxes, laying against these boxes there are two guns an FG42, and an MP-40.
