How is Nightmare Difficulty Different in Orcs Must Die?

Question

I just finished beating Orcs Must Die! in the middle difficulty. I was considering playing through in nightmare mode, but I don't care to if it is all the same levels. How is nightmare different?

Answer 1

Yes, it is all the same levels. However, they are significantly more difficult because:

• The enemies that spawn are significantly more difficult (more heavy orcs, ogres, etc)
• Your traps and weapons do less damage
• There is no wait time between rounds
