Nope BB I was wrong about that - it's pretty much the same as JO/DFX's. However even though it's the same engine, the new .exe has had a lot added - widescreen support, way better network code, etc. etc.
Basically DFX2 is just a way more balanced and funner version of DFX. Yeah I know it sucks that the same assets are used and the same AI is there (completely re-working the AI would take a crapola-load of time, not to mention there may be certain engine limitations), but just hope the overall gameplay will compensate for that.
When I played Cloak and Dagger it was a pretty alright mission. Like I said, I don't like that environment, and it can look way way better than what it currently looks like (and I know this for a fact because I've seen some kick-ass environments on this same engine).
And of course the weapons are pretty much all nicely balanced, online.
