It's better than Vegas 1, a lot better. It still suffers from random bullshit like guys spawning and popping out of nowhere and console like aiming (seriously, shooting in doom 1 is easier). Just to elaborate on my last point, it feels like your sights move in increments, it isn't smooth at all. And slow nades, flashbangs, etc. I don't know what Ubisoft is thinking since it's still zero-g when they're thrown.
At least they fixed the number of checkpoints, by adding more, which lessens the frustration involved when it comes to dying and starting all over again.
