Pros:

I have already played the version before and to be honest not much has changed ,apparently versus changes but as I haven't had a chance to play on versus ...
I didn't post a review on the older version so here is what I think 

-One of the few cool versus maps
-exciting
-no flaws for me or gamebreakers or glitches
-perfect lighting
-adding an extra map =awesome touch
-good lenght
-fun final

Cons:

-as always nav issues
-easy to camp on the final map

Conclusion:

An overall very solid campaign.thumbs up
