Technically and mechanically sound (apart from the netcode/server stability), but I'm not feeling the pacing and map/mode design, personally. My tastes have probably changed since COD4, but it just feels too aimlessly run and gun to me thus far; not much direction or method. As beautifully done as the weapon mount mechanic is, sprinting around the map until you see an enemy or they see you feels like the superior tactic. Maybe I'm just getting old and slow. I'll keep playing to see if it warms on me.
As someone that plays CoD every year this is the least run and gun CoD in awhile. Thats one of the reasons i'm mixed on it because that's my preferred playstyle.
