Deus Ex: Invisible War Preview

Ion Storm's Deus Ex: Invisible War won't be on store shelves for a couple of weeks yet, but Firing Squad has a hands-on preview to get you started. An excerpt to follow:
When you finally get down to the action, it's a pleasant surprise. The combat won't wow anyone, but the planning that goes into setting up an encounter will. Since you're intent on conserving as much of your health, ammo and bioenergy as possible, you'll try for the easy kills or no kills at all. Every encounter is like a puzzle, but in a first-person shooter. The only other comparison we can think of is Thief, where you make do with limited resources. It's not surprising then, to recall that ION is working in Thief III.
