Pretty freakin good
the campaign wasn't long but it seemed a little longer than mw2 and it was very interesting.
have found a few glitches but not to the number of mw2
balance issues are being worked on...some smgs are a bit overkill
however...it's fun..lots of fun.
then again i preferred World at war to mw2...so maybe this is a little biased

but i say get it..
