Been playing it. My favourite part is where it tracks shots fired. I've noticed that the most I've shot in a single round was as support is 75 bullets. That seems pretty low. Still, had 8 kills that round. And another round I had 17 shots fired and 5 kills with an AK. Most of the rounds I spend between 30 and 60 bullets.
The sound in the game is fantastic. When someone is shooting at you, you're terrified, because any of the bullets can kill you and then you hear the awesome sounds of bullets hitting the wall next to you and your vision gets all blurry. Being suppressed is actually a thing in the game.
Another cool thing is that on some servers it doesn't tell you whether or not you killed the guy, and some servers even have the scoreboard turned off so unless you saw the guy go down, you can't be sure. Which makes moving around terrifying. The scoreboard also doesn't tell you how many enemies are alive.
All moving is extremely dangerous and if I'm heading to an enemy infested area and generally running inside a room and attempting to gun down the enemies will get you killed instantly. Grenades are your friend when moving toward the enemy.
I don't know. To me it's great fun, especially if you find a server that actually plays together. It's one of the best multiplayer FPS experiences I've had in ages.
