Pros:

- nice sceneries with Japanese twon and temples
- detailed map 

Cons:

- some places without nav mesh 
(ex: above vans or vending machines)
- survivors can collect gas cans before the finale starts
- several error objects around the map

Conclusion:

Overall, its a nice work. But need to fix some bugs and errors.

Pros:

Great details,

Sync is perfect,

 it is just awesome!

Cons:

having a bit trouble distinguishing each survivors

Conclusion:

Just go ahead if you wanna play L4D2 in millitary mood. It fits perfectly to the survivors.
