"Necropolis" - changes to creatures of levels 6-7.

I think the zombies in Necropolis could be replaced with something else (both in terms of balance and, most importantly, in terms of appearance).

So, what would be the cannon fodder then?

Zombies fit well into Necropolis. Each faction has its own kind of "slowpoke," durable but not very smart, and this is the case here. And, indeed, what would you replace them with?
