I know what you mean about the 'inbuilt ninja' as I play with headphones, and listening for footsteps was a real part of my run and gun gameplay. Anyways, some reckon that Treyarch will listen to complaints about the sound and address it in a future patch so heres hoping. For now, I wont be using ninja in any of my setups.
On the , online multiplayer is still a bit of a joke. Stuttering throughout, with some servers possessing what I call UBER lag where the game runs in slow motion. Everyone experiences it so its fair, but it's bloody ridiculous.
And then there are some signs that show that this game is lacking some real polish. Bugs like the game somehow forgetting that I already bought 7 layers to edit my playcard (w/e it's called) and now if I want to edit it, I need to buy them again along with anything else that I used. The game still refuses to record my matches. Annoying. And then little things like the images for perks being horribly stretched at times as if the image was originally way too small, and the exp bar overfilling to the point where its telling me i need -6400 points to level.
All that said, I still plan on playing as much of it as I can these coming few days. The maps are class. Much better than MW2. I think it has really changed the way some people are playing. And some of the killstreaks are genius like that dogs. Really want to get that in a care package drop soon.
And haven't touched single player. Not sure I will as I never did in MW2, and haven't played a COD before that. These days, FPS games are all about the online multiplayer for me.
