Just beaten this, thoughts below:
+Looks decent
+Solid performance 75-125fps
+Good configuration options for FOV, framerate cap etc
+I quite like the weapon / ability customisations and level-ups
+Lots of fighting alongside AI teammates which is good
-BO series plot still doesn't grab me, I enjoyed all the other games in the series but just can't get engaged by these storylines
-Not enough variety of enemies
-Seem a bit OP with your abilities, mass of ammo crates (I hardly ever used my sidearm), implant to resurrect you etc
-Would have been nice if it forced you to use a wider range of abilities, I just used Chaos all the time; I found myself missing the tutorial sections.
Overall I can't imagine I'll want to play through this again.
