Ok here is my opinion on it:
I love it! but it has some issues
First of all I love how many tactics seem to work, I love to lay down dead and people just pass by so i follow them and CQC them... and I've seen many good people that are stealthing really well.
What i really dont like a lot is the shooting... it seems a bit odd and i just cant seem to do enough damage with it, maybe i just plain suck and I am better off stealthing (which i got pretty good at :)).
Other minor complaints and this is not on the game but on the people playing:
1) this is not Cod:4 or Halo! Don't just go around like rambo and shoot shoot shoot, IMO this game is meant to played in a much slower pace. But i still see people that haven't even tried to be stealthy all they do is run, shoot, die, repeat... Then I'd see why you don't like this game...
2) If someone is CQC another person don't just shoot the enemy... come on i've been team killed countless times because I was chocking a guy, a team mate wanted to steal the kill and got me instead killing the enemy and me... so not only have i lost a kill, i also gain a death (which takes off points) and the team loses a ticket... just wait until i have stopped or the guy is free, seriously.
Anyway for the rest i really enjoyu it and the maps are good, even if blood bath is a bit small and isn't easy to be stelathy... the best you can do is lay down dead and wait... oh well
Here is a tip for CQC on how to roll over when yoy grab a guy:
So grab him and press X like this you will sit down, then stop pressing R1 and immediatly press R1 and left on the analog stick, you will roll over. This is really useful because if you start chocking him (pressing triangle) his stamina bar will start going down really fast and if the guy gets free, he will be laying on the gorund and you will be ready to shoot him or CQC him again, stunning him for sure!
Hope it helped!
