I'm actually embarrassed at how far backwards they went with this game. I usually like Treyarch far more than Infinity Ward but this game feels like they took World at War and just reskinned it. The graphics look like CS 1.6 with less sharp edges. The gameplay and gunplay just feel off and I can't really put my finger on what it is. It also suffers from the classic Treyarch SMGs where they far and away overpower all other types of guns. There's literally zero balance between the weapon classes. And the attachments? They don't even make sense. I could run a gun with no attachments and it feels the same as if it has attachments. Foregrips don't even help that much and everything has horrible tradeoffs.
They should really just delete this game and try again in 4 years.
