I used to play it occasionally cuz of a real life friend wanted to play with me, in my opinion the movement is awesome, but yes the movement is pretty choppy.
A game like call of duty that has movement like that shouldn't be a thing, you can't make a game that makes every gun take 4 hit-points to kill someone and always jump in the air.
I got bored of it within a week lol and i play it like once every week just to keep playing with my friend (oh well).
I don't suggest it, unless you can manage to do super well at it in a week and stomp everyone. I think there are a few hackers that use this really op laser gun, i call it quad-damage lg.
