I'm liking the beta, i'm on lvl 17.
I wasn't sure how Treyarch would do on this one but i knew that being built on the COD4 engine would give it a good foundation and im prob gonna pick it up on release, it's good fun.
I would expect, or hope, that they remove that glitch in Roundhouse. Don't get me wrong I don't like glitching, though i did get a whole team into the glitch which was pretty funny, but that was for novelty. I can't imagine how someone found that since you have to crawl into a brick at such a strange angle.
I hope they up the cap so i can get the russian PPsh! (I kind of doubt it though) At the moment im using the silenced mp40 (mid) / muffled svt-40 (long).
