The Bureau: XCOM Declassified takes the principles from Enemy Unknown but puts you on the ground as a squad leader. You're still issuing orders, trying to flank enemy positions, and deploying massive firepower against a multitude of aliens, you're just doing from a conventional third person perspective that allows you to fire your weapon and move like a more conventional action game. The best of both worlds? Perhaps. Today's trailer shows the player taking down enemies without ever firing a shot himself. That's a pretty good sign.
For fun, feel free to check out The Bureau: XCOM Declassified on Facebook, and then check out XCOM: Enemy Unknown if you haven't already because you should.
