I downloaded this a couple months back. It's basically an upgraded editor that doesn't make maps for ut3. instead you need to make the games yourself with a mix of unreal scrip, custom assets and the new editor. The generic browser is also given a much needed update, but nothing really new here.

Is anyone of you guys still using UDK for anything? I started some days ago and it's really fun. Sad enough the UT3 editor isn't getting such contineous updates and new features ...
Dunno myself as I never played it. I know one of the UT3 patches had a 'rocket arena' map in it. I'm moreso thinking that as there's only 2 weapons in UDk. The Rocket launcher and the shock rifle IIRC.
