Our favorite improvement by far has got to be the introduction of the A.C.E.S. But do those issues really impact the experience that much, or can you expect the same caliber of tactical gunplay that monopolized Xbox 360s and PS3s over a year ago? We're going in. Yet the absence of four-player co-op in the story mode is noticeable and disappointing and there are clearly still some things that Ubisoft Montreal has a difficult time dealing with (remember the sound bugs from Vegas?). While not a giant leap from the first Vegas, Vegas 2 hits most of the crucial points that made the first game so popular. We've put an incredible amount of time into playing Rainbow Six: Vegas 2, and we can honestly say that we'll be putting way more time into it in the future.
