I liked all the new maps which is rare for me. Although I am tired of grind. I always buy all the new maps just to keep the game from getting stale. However I have decided not to buy the last map packs anymore. It is pointless for me, because it is always released right before a new COD game comes out and I move on to the next game. SO it is just a waste of money.
Grind and hydro are some of the best maps ever released in a map pack. The other 2 are hit or miss for people but I like them.
