On A Mission - MNC Recreation Idea

I've been working on trying to make a replica of the MNC map Grenade III in ''Halo Reach'' but I've been having some difficulty. Reach seems to have lacking of curvy shapes so its very difficult to make a whole round arena. I'm probably looking on switching to making the other maps [except the Dome one] but I still cant seem to find very big open detailed pics showing all the spots around the map so I know exactly how to replicate it right.

I have also checked on the MNC wiki page http://mondaynightcombat.wikia.com/wiki ... ombat_Wiki

but the pictures they provide are extremely tiny and dont have very good resolution

so anybody mind helping me out? =)

I think this one shows it off good.

AmmoMule Arena I think. All of the game is pretty curvy though. :?
