If You Haven't Tried The Map, Be Sure To Check It Out Here: http://www.planetminecraft.com/project/zombie-training-map/
If The Link Is Broken, Just Go To My Projects Area.

MY ADVICE: Go Around The Map As You Casually Would, And Be Sure To Jump Off Things, I Put Things You Can Jump Off Of For A Reason. Oh And You Want To Go In Circles Too...

You Probably Want To Install A Teleporter Mod (Team Fortress 2 Teleporter Mod Works Better) And Make Two Teleporters To The Mainframe (The Lanterns At The Spawn).

I Will Add The Teleporters... Just Install The Mod.

That's My Advice To You. Thanks For Taking This Into Consideration.
