New maps, some I would suggest -
*Prison/asylum
*Volcano (the heal base is in it, plus you can climb it)
*Airport (sort of the like the infected one, sort of)
*Village (Some loot would be in the chests of the houses)
*Bedroom (You are in a very large modern room where you are depicted as very small)
*Forest (add a few temples too)
*Meepcraft (use the spawn we have and block off some of it) -maybe
*Military base (like it says)
