There are plenty of problems, the animations are horrid, the characters look like they're sneaking on their toes when they move, the shooting lacks "impact" and the entire encounter consisted of blindly spamming rounds which is lackluster for a supposedly tactical FPS (their claim not mine).
BF3 isn't even considered a great FPS, just a good one and you can't even compare the two. This is why it puzzles me they invested in what's essentially a FPS minigame, if you don't have the resources to get it right, why bother?
