Gamespot have posted their Unreal II: The Awakening Impressions. Here is part of what they had to say:

Producer Matt Powers was on hand to demonstrate the build, and the first level he showed was of an alien planet overgrown by a strange, purplish jungle. A group of mercenaries has discovered a mysterious power source on the surface of the planet that's almost organic in nature, and your job is to infiltrate their facility, investigate their discovery, and then escape with your newfound data. The mercenaries run this planet, and they've left it bristling with automated defenses that you'll have to deal with. Your primary objective lies behind a massive wall whose only opening is blocked by a force field. Atop this wall are a number of turrets that automatically track and lock on to you if you get too close. It's here that Powers was able to demonstrate some of Unreal II's weapons. To dispatch the turrets closest to him, he selected a standard grenade launcher, whose explosive munitions eventually tore through the turrets' tough armor. To contend with the defenses that were farther away, Powers switched the munitions in his grenade launcher to an EMP charge. These grenades took out their targets with one hit, since their electromagnetic pulse penetrated the turrets' armor and fried their circuits. In fact, the grenade launcher can fire six different types of grenades: explosive, electromagnetic, toxic gas, incendiary, concussion, and smoke.
