Rainbow Six: Vegas returns to form as an excellent tactical shooter, but is much more accessible for the average shooter fan with streamlined controls and a simple health system. The sprawling levels like the glowing Fremont Street or the Hoover Dam open up Rainbow like it's never been before, and the result is a balanced shooter that is as much close-quarter combat as long-range head shots. The new gameplay mechanics, notably the intuitive cover system and inverted rappelling, are simply outstanding. While the visuals are solid, the textures and colors are muted and appear washed out. The sound, on the other hand, fuses a pulsing anti-terrorist soundtrack with gritty dialogue -- "I will f***ing shoot you!" -- and even some humor -- "Hey man, you play videogames?" The multiplayer options feature huge, well-designed maps, a variety of modes and four-player co-op. In total, Rainbow Six: Vegas is the best first-person shooter on the Xbox 360. Viva Las Vegas indeed.
