Skyline and Pier17 obviously..... they're the only two maps in the game that are actually made for multiplayer. All the rest are campaign maps that just look pretty.
As mentioned, Skyline is in game, but it's not only Pier 17 that's original, Liberty Island is too (split into Statue and Evac in deathmatch modes)
I don't mind them using campaign levels, as by and large they're all excellent for MP (unlike say in Reach) and are all altered considerably.
Also TC, you've missed the split Liberty ones and Parking Bay in your poll options.
bollocks I knew I forgot one.
Just remembered - you've also missed out Downed Bird.
