Get out of 'Nacht Der Untoten' map
Go into the 'Help room' and look around. Get a gun that lasts it's ammo for a long time and walk up to the boxes near the zombie barricade round the corner of the help door and run into the little space between them that you can't fit through. The game will lag for a bit then while it lags put the charger in.
To get the flamethrower first get 3000 points or more. Once you have all of the money remove the baricade to get up stars. Now you have 2000 points (or more). Go forward into this big room. turn right and you will see some fire. go to the fire. There will also be a new gun. Turn around to see a red cabinet open it for 2000 points to get it.
use only your knife thru level two then between level two and three get the mystery box and you will get the ray gun.
Open Doors Without Using Any Points
To open doors without using any of your points you have to do this. First you must be with another player or you'll just die. Start a new game with someone else either bluetooth or anything else (as long as it's not single player). Once you do, go to any door (on any map) and see how much points you need to open it. Then get that many points or higher. Then go to the same door. Then pull out a grenade and keep holding it while counting from five seconds to one second, then wait half a second more and press the open door button. If done right, you should throw the grenade and open the door at the same time. You will also get downed. Then your ally should be coming to revive you (most of the time). If they revive you, you will see the opened door and your points will be the same.
Get The Ray Gun And Wunderwaffe In Round 3 (Shi No Numa)
First you have to get 2000 points to get started. So I suggest knifing the zombies until round 3. Now, go to the Mystery Box (where it starts off) and buy a gun. When the Mystery Box opens and you see the guns flipping and changing. Quickly run to the door way on the left side of the box and hide on the side of the door frame until you can't see the changing guns. And when it stops. Go see what is your final gun. It will either be a Wunderwaffe DG2 (a gun that shoots electric bolts) or a Ray Gun. Note that you only have a 50% chance of this working, so in the first or second level, open the gate so when you are trying to do this glitch, zombies can't attack you from behind because of the stairs that you might have opened.
This is for nacht der untoten. You need to go to the mystery box and to the left. (in the corner between the cabinet and mystery box) look down and try to plow your way through the gap. This is very fidgitty, and I found it helps to play music and also quit the app while walking in the corner and resuming the game. Neither of those are required but they get you through faster. (if you don't have IOS 4 you can play music by starting a song and then the app, then right as the opening video is starting double tap the home button and the player bar should come up, then just hit pause and play, if done correctly the video will be skipped.
Invisible To A Zombie
Unlock the "help" room. Once there, unplug your charger and plug it back in. To exit, do the same thing as you did to get in. Note: You are invisible to the zombies the entire time. If you are having trouble killing them, shoot up and you will get a zombie or two.
Good Mystery Box Gun
If you use the mystery box on round 2 you normally get much better guns. DO NOT use it on round 3 it sucks at least wait till round 4. The above is true but I only think that even numbered rounds are better for the mystery box than odd numbered ones.
Survive Nacht Der Untoten
After you get enough money, remove the debris to go up the stairs to the balcony. Look for the box that sells grenades and stay there during waves because you have your back protected and you can see the whole area.
