This map is based on the L4D2 map called Atrium (http://www.youtube.com/watch?v=LrzQXC7hQ78) but it's set on an atirum on Theed and the Death Trooper (Zombie) infection is there.
Sorry the screenie is so dark. Should be released in a few days along side some Zombie gameplay tweaks on ESM Zombieland Classic that I'm thinking about. Hopefully it'll revitalize things a bit.
I'm thinking about adding a difficult to get to objective for the survs that will allow them to end the round by achieving this objective. That way you could play 'standard' Zombies or try to end the match if you so desire. No solid details yet... still sketching ideas out.
