The last maps have been released for MW3. Gulch, Parish and Boardwalk.
For those who did not subscribe to Elite, then you also get to play on Decommission and Offshore.
Parish, is a really small and tight map. Very basic, and only handful of small paths that basically cut through a large ring. There is no elevation change, no second story building or hallway to get a higher vantage point. It is a fairly hectic map given its size and you can really catch the other team just off their spawn if you time your run through properly. Its very easy to get over run in a position because of how fast it is to get from one side to another.
