monkey boy will add later – my psn is itreallywasntme
My strategy for der riese from the top is rounds 1-3 don't open any doors and use pistol and knife. 8 shots in the leg followed by a quick swipe with the blade gets you 210 points per zombie. Try and let them out so you can get the bonus's, max ammo and double points is especially useful here.
Rounds 4-10 ish I camp near the first mystery box location and try to get a decent gun, monkey bombs, quick reload and jugger. After that its camp on the stairs above the bowie knife trying to leave a crawler at the end of each level by throwing a monkey bomb out of the window to get the remaining perks and a papped ray gun and mg42. The wonderwaffe I just can't get used to.
That vid posted on avforums is where the guy flicked between the double tap area and teleporter c with a flame thrower and papped ray gun. He gets to level 41.
