3. shoot mangler's gun. it gives you 200 points per kill.

4. careful where you stand, it may be a mangler spawn point and they instant spawn so it will be on top of you.

5. panzers on tight map is no joke, priority is to have powerful setup to kill em and safety perks to save your life. wunderfizz is bait earlier since you have to ignore the fun perks.
first panzer, you can kill easiest with m1 irons + speed + doubletap.
this is why you rush krm pap for most consistent panzer killer gun
