Going one step beyond X05, Microsoft had a near-complete build of Perfect Dark Zero on the floor with all-new never-before-seen levels. Since we had free reign to pretty much play however we liked, we grabbed the controller and did what comes most natural - start from the beginning of the game. The first level of Perfect Dark Zero is your typical tutorial-style mission, complete with contextual excuses for teaching you how to duck, roll, pop out from behind cover, and hack open doors. What really hits you immediately is how damn gorgeous the game looks. As you walk around the enemy compound, half of which is under water, you notice all sorts of environmental details like the visual warp of looking through liquid, or tracing wires and cables to the machines they're hooked up to.
Although the mission is initially an infiltration sortie, you'll end up going Rambo on a bunch of targets, including hordes of robot spiders and enemy agents. Even more impressive was when we reached top-side of the base and were greeted to an entire platoon of enemy troops, all of whom left exquisite corpses behind after they were shot. The Xbox 360 could clearly push all the polygons and visual effects with muscle to spare. The mission takes you across the surface of the base to a series of platforms. Looking up, you see the epic height of a massive space shuttle getting prepped for takeoff.
