hey i am a fellow mapper and nazi zombie enthusiest and would like to say that i am working on the designs for my own map at the moment it is sort of not done yet and certainly unorganized however i am off to a great start based on how many times i completly failed at making any other adventure map. if you'd like to see how i am doing i can tell you already
what i have done so far:
-made a tellraw that teleports you to 4 places before starting the game
-made the outlines for a few of said places
-created a special arena that will give better loot than the rest of the map
  -uses creepers with wither to create a challenge
     -wither kills the creepers after they have been tp'd out
  -creepers may drop an enchanted helmet (creeper face) 
-created a fairly well working zombie barrier
-a power generator
  -requires the placement of batteries for the use of electricity, may run out after a while but renewable
-score system
  -downs
  -kills
  -health
  -points

When i look how far you've come yourself and i look at myself, i see that i just have lot more i can improve rather than i could never be as good as you, i would like to use some of your designs however such as the chimney jump boost. either way when i release my map i will certainly link to both of your creations and hope we both may get along fine.

p.s. let me know if it's alright to use things like perks and jump boosts from you're game and incorperate them into my own creation.
    thanks for you're consideration

When will this be done?

Wow this sounds awesome

awesome work, cant wait to see it when its done :)
