Funny thing is no one noticed the things that got changed as a result of there pain staking complaining in the demo. First two things I noticed in MP is that nano vision has a range limiter, so any player within a certain distance can be noticed but outside of that range is grey on a grey background making that player harder to see. Another change that was made was the alteration of shot gun damage. I can now roam the corridors and tight spaces of skyline and some of the other new freakin awesome maps and raqe face.
And the best part is it only gets better from here! With patches and DLC releases, looks like a bright future for me. Everyone needs to just settle down and enjoy the game, cause it's fun.
