If you downloaded the beta yesterday, you may already know a bit about the Orks in Dawn of War 2. Gametrailers takes a look at the class and some of the units. Mostly it just shows a bunch of green dudes smashing and destroying the crap out of everything.
And that's totally awesome.
If you haven't checked out the Dawn of War 2 beta yet, I highly recommend it. It's a great action oriented RTS game - one in which the full one will feature a co-op campaign. Perhaps you read our interview?
