Yerr it does but it dosnt have to be one dude and his mingun with 3000hp. It could be multiple SWAT units with smarter AI who can flank and take cover. Although it would probably take a lot more to implement such a thing.
I also hope they can find a way to reward teamwork rather than just one person carrying his team.
Apparently they are planning on releasing it in Q3(august).
I agree. It should be an optional download and not compulsory as the download would be quite large, plus it would be useless for people who wont ever play it. I hope they make it like an expansion pack.
