the best DLC CoD has had in my opinion,i like all of the maps other than HYDRO thats my worst...the peacekeeper is a good gun but it gets boring because everyone in the game is using it! Its not the best gun in the game,but no where near the bottom of the list.
New maps are great i'm a quickscoper and the best map for me is Grind the peacekeeper is a OK gun but it has such a low fire rate for me rapid fire is a must have I use the DSR-50 theres like no hit markers.
Hydro - my favourite only because I'm good at it lol. Plus it's a great map with good areas to switch up tactics
Grind - like it because its new and fresh and generally a great map
Downhill - like it because its good for sniping (although I'm not a sniper) and there's snow! Yay!
Mirage - I'm pretty good on this map (I was terrible when I first played it) although its my least favourite, too much sand
