Pros:

-It plays in campaign and realism so you can change difficulty levels
-Still challenging even with the low levels of special infected presented by campaign
-low gravity makes for interesting gameplay
-TONS of things to build and unlock

Cons:

-Bots can't help unlock things
-Survival mode is impossible
-No Stats!

Conclusion:

The Pros far outweigh the cons, and I have played for hours on this map with friends!

The lack of stats is a little disappointing, though, because I feel like I've killed a million zombies.
