1. Hate, hate, hate.... some of the sound effects (mainly grenades and a few guns). They sound weak and pack no audio punch. I have, imho, a very nice and capable A/V set-up and just wasn't feeling certain sounds. Now I've only used a limited arsenal, so I hope it's limited to grenades and those few eaons I used.
2. Very glitchy. Not sure if it's lag or what, but something nees to be done... the sooner the better. My internet connection is GODly (see the FiOS threads for my speeds, though I don't have FiOS myself). I don't know if it's something that can be fixed, but I sure hope it is. I had the drop on a guy with my smg (he didn't even see me coming) and put a few shells in him (3 or 4) from about 15 yards out, he dropped and I thought he was dead... but he went into last stand. I closed in and strafed him as he attempted to shoot me with his handgun (he missed all shots as I was moving too fast around him and he didn't keep up) and so I whipped out my handgun and put another 2 or 3 shots from about 8 feet out... For all intents and purposes he shoulda died (again) but nope, since I had closed the gap on him he simply fucking knifed me. I honestly hit him with 3 or 4 smg shots from close to medium distance, plus an additional 2 or 3 shots from really close range and he still didn't die? REALLY? All I can attribute that to is lag, but it didn't look or feel laggy at that moment... I really hope it was lag and not something wrong with hits registering or off calculations.
3. Spawns sucks. Just so helter skelter. No flow, no sense. So random.
4. Not feeling the credit system. Hope it grows on me.
Aside from all that, I kinda enjoyed the game. I already enjoy it more than W@W's MP. MW is still the gold standard.
