I think it fails quite a lot to be honest - it's a bottleneck of a map, in other words long and very narrow indeed. The lava is downright tedious. And the little midget zombie is just a pain, not a novelty. He is the Jar Jar Binks of the zombies series, they should patch him out.
The one thing i liked about the earlier maps, was the easter eggs were simple and rewarding - shoot a radio, find a teddy bear, pick up some meteorite to trigger a tune.
But the easter eggs have just got ridiculous, and the lion's share of people jump into a game and dont mic-up with strangers and then all co-operate to do a challenge. Sure if they want heavy easter eggs, fine - but dont kill off the simpler ones for casual gamers.
With regards the actual action itself - For me it loses it's arcade-fun element, it's too fussy and the novelty has really worn off fast for me. I hope this is just a taster and that the downloads make it colossal and fun. But right now it's plain tedious.
Even a simple, but absolute killer map like Verruckt wipes the floor with tranzit. Verrukt is pressure and survival - this is just a nonsense and racking up kills is no longer the focus it would seem.
