Possibly the most advanced MBF21 so far. Pretty damn fun to play as well, though you'll need to get used to the new weapons.

I also stuffed the 16:9 statusbar from BTSX E1 into this. While the mod does have a SBARDEF-defined HUD, UZDoom won't display it at the moment so I just did the next best thing.
