It's had a terrible start.
At first glance, you'd think it was a game ready for very good things, but it stops there.
The map designs for the most part are awful - It's a camping haven
Footsteps are laughable - Running round with lead boots on (Campers love it)
The hit detection was off to a real shaky start (Not sure if fixed)
Although I didn't mind time to kill, it did feel on the shorter side of acceptable
Oh, also, it's hard to sneak up at people as your character decides to announce to the whole map you've just seen somebody
For the most part, it's the community that ruin the game, but all the features right now are there to be taken advantage of.
They also tried a similar game mode to Battlefield, ground war.... All that is, is 20 snipers, all on the 20th floor roof, just sniping and not going for objectives.
For somebody to say, people complaining about campers 'just need to get better', thats a lie. The game right now promotes it so much, that you're forced to either camp yourself, or run around and hope you don't get shot.
Dark corners in buildings, loud AF footsteps, claymores and low TTK means that sitting in a corner is very easy to do.
You just need to watch the numerous videos, parody's, reddit pages.
As for other CODs having camping, that is true, but it was never this bad, unfortunately
My opinion of course
Oh, slight edit. There's only two guns on the game
M4
The Shotgun Sniper
