Terrible game. I'm not going in depth with this review (others might) but I will say this.
Sbmm...
In other words skill based match making. Sbmm (skill based matchmaking) is when the game matches your skill level with other players in your region.
At least it attempts so...
Since sbmm is so strict, most players can get 1-9 kills on average, which is barely enough to get 50+ sr (with a top ten placement*required). This way it would take hundreds of games just to 5600 Sr (platinum rank). This sbmm almost ruins the fun because wherever you have a good game (10+kills) you will get harder lobbies making it so you can barely get 1 kill, and lose rank.
Also, cheaters are also a big problem in call of duty. Cod mw3 has turned into a sweatfest and cheaterfest.
I have a feeling bo6 will eventually be the same.
