Pros:

Machine Gun in first part in finale takes alot of trouble out when it comes to the two tanks and mega horde.
Decent traps for tanks popping out of no where and witches.
Explosive ammo after opening the door in finale.
Challenging.Its possible to lose this even on normal.But that's the fun.

Cons:

No actual traps that kill you instantly.
Bots refuse to take health packs or Tier 2 weapons.
Too many witches and tanks  for my taste.
Special infected attacks are rare in finale.or is it just me?
Mega Hordes will lag you.
Impossible to beat on expert,let alone expert realism.There are just too many hordes.
Traps dont change.

Conclusion:

A great map,despite no actual traps.Constant horde attacks and probable tanks keep you on your toes.
Witches appearing out of thin air with smokers?Increase smoker reaction time,They stand there staring at you stupidly before pulling you to the witch.
its still fun,especially watching first timers screw up over every trap.
