1 Kill count...like the little number up in the corner and every time someone dies it goes up 1.
2 Maybe it was just my PC lagging but it looked like it was sometimes going in slo-mo at unesecary times...and in the other one when it did go slo-mo I really like how you could see the bullets as they came out and hit the person not just a white line.
3 I completely LOVE it other than those two things...
