Ive had two hard lockups and 3 lost connections. And only ONE game. Anyone else having this issue? 

A few times while I was playing it took a few tries to get the MP demo going with finding a match open. Stick with it as it's not too bad once you start unlocking things & it is an unlimited time demo as far as I know (though you will hit armor/stealth/power rank3 & overall rank 10 as a max in the demo).

I'd be interested to know how many folks here on GB are still having issues. I've been enjoying the matches I've been in, but I invariably get kicked out or there's heavy lag.

It freezes my xbox about most  of the time. I've only been able to play 3 matches out of 30 or so attempts. I was really looking forward to buying this game too. Not so much anymore.
