Pros:

nice map layout
great detail and mapping
good sounds

Cons:

glitches in maps
3rd map in toilets, sinks have slight holes as looks like miscuts done.
finale unfinished as unable to complete it. Yes i read about the glitch in it.
not enough ammo placements as run out of ammo quickly.
More weapons on 1st map as pistols only make it hard especially when tank arrives

Conclusion:

Overall a great map but need to sort out the glitches.
Love the sniper type zombies but needs more ammo for the playability factor and feel limited to just pistols for so long.
Get the finale sorted and it will be an even greater map
