Ok this may be sudden and new from a new comer from me but I didn't play this yesterday or today. My name on the game online in iPhone version of zombies is pitchblende and I have spent lots of time in der riese to know everything so here goes how to survive in der riese you start off wif a gun and a knife shoot a zombie two times before knifing it for best point results. When you feel like it open up the door on your right dun ever do the left if u are playing solo and feel like glitchin smash into the side of the pipe near the stairs and wooden door and pause resume till u see the barrier and looks as if ur stuck in the wall then exit and get to the other side saving lots of points and allowing the barrier glitch if u r not a glitcher just go along legibly and open up the mystery box near the on switch usually u have a 50% chance on a browning m1919 mg-sum thing(I forgot) ray gun wunderwaffe ray gun or a monkey bomb it hardly will be a useless weapon on your first try if u did this on round 3. Grab ur gun whatever it is and put up ur resistance till the hounds appear kill E'm and proceed to open the door near the mystery box turn on the switch and link the teleporter try again on the mystery box if the weapon you carry is not a wonder weapon. Build up your points and rush for the rest of the teleporters at the right and left next keep trying on the mystery box till you get a monkey bomb and a wunderwaffe NEVER SWITCH YOUR BASIC PISTOL THE POTENTIAL IS MORE THAN YOU KNOW get the wunderwaffe and upgrade your pistol why? Cause it becomes a stielhangrante launcher that blows up instantly and can help slow zombie traffic cause the bomb turns E'm into crawling zombies next rack points up for your wunderwaffe upgrade and the rest of the perks except your quick revive(useless in solo, might be useful in quick reviving teammate in co op) and YES GET THE DOUBLE TAP!!! On the later stages you will need spam a lot and don't WAHH WASTE MY AMMO AND STUFF you will get max ammo on every 4 or 5th round by defeating hellhounds go to the end of the stairs of the tele porter near the power switch not near the window but the Teddy bear area camp there and survive for your desired rounds. Tips: 1.Try to get to the mystery box by round 3 good guns happen during round 3 and hellhounds happen usually round 4-5. 2.Never switch the pistol for anything the upgraded pistol is as good as getting a zombie with your starter granade and better than your ray gun. 3.When playing co op DON'T BE A IDIOT THINKING YOU'RE PRO TRY AS MUCH TO HELP YOUR TEAMATE EVEN IF HE'S NOOB UNITY IS STRENGTH unless you are swarmed and it's difficult to get to him. 4.Always stick together when playing co op this way you cover the guys back he covers yours 5.Don't killsteal stick to your window or if your teammate goes to yours you go to his. 6.Do not attempt the bomb open anything glitch when you know it isn't safe at all this will create trouble for teammates that can easily be swarmed. 7.when you get a max ammo during hellhounds make sure u and ur teammate reloads everything b4 obtaining the power up MAXIMISE YOUR AMMO. LASTLY DO NOT LEAVE DURING A SWARM PROVIDE HELP YOU'RE RUINING THE FUN OF ANOTHER PERSON(S) AND THEN WHEN YOU JOIN A ROOM DON'T LEAVE IMMEDIATELY PLAY AND HAVE SOME FUN TOGETHER! Oh yeah and IT IS POSSIBLE TO HAVE THE WHOLE TEAM ALL ACQUIRE WONDER WEAPONS So keep trying the boxes! Have fun soloing or cooperating. Questions postem below
