Minecraft Vanilla C.O.D. Zombies Map

This is possibly one of my favorite creations I've ever built. It's based on Natch Der Untoten from Call of Duty World at War but isn't exactly the same in layout. It has four rounds, plus one bonus round. Weapons are available to buy as well as ammo (arrows). Weapons are "The Huntsman" (Bow), "Bowie knife" (gold sword), and "The Huntsman 2.0" (power 3 bow). It seems quite simple but I'm quite proud of it as I'm not usually that good with redstone. The redstone pulse generators will have to be rebooted from time to time (not sure why) so just open it to LAN with gamemode set to creative and cheats on. This will allow you to reset the redstone but also to change back to adventure when you're done. The full rule-book is included in the map (don't look for it in the download file, it isn't there) and will tell you a bit more about the map. This is my first creation on PMC and feed-back would be appreciated greatly, so long as it's constructive and not too harsh. Ideas for improvements are welcome but keep in mind that redstone isn't my specialty. The file is an MCedit schematic as I haven't taken the time yet to make a media-fire account. In any case... enjoy :D

P.S. it looks the coolest (and most authentic) if you play on tine render distance.
P.P.S. I still new at this, but I don't want to forget to credit soooo... um... Credit to treyarch I guess... since it kinda looks like natch der untoten... sort of (Probably didn't need to do that but whatever, better safe than sorry).
