Yes plenty of repetition, but i still play it and play it and play it and play it. :S It bothers a little, but the next day ,if you have time, you're there again shooting enemies. And weeks pass.
Or not and you hate yourself for buying this after you're done with story mode, because PVP kicks your ass and coop is too repetitive for your liking, bounties repeat to often and you never get the gun you want.
Then again you weren't on the hype train so you couldn't be as disappointed.
