I wont be able to name lists since I haven't played the game loads, but
I don't really like nuketown since it's such a close quarter map with no proper tactics. It's a good map for a private match or just lan party. But joining a server with 8+ players is just chaos with random nades flying everywhere.
I'd prefer something with a lil more size, but still not open areas so everyone get their snipers and just crawl into a corner for the rest of the map. It's something I dislike, I want flow like a river.
The famas is pretty good in that game. But I'd probably prefer the commando or ak47 over it.
