The whole general atmosphere, the concept, is amazing. I'd say it is one of the best squad-based strategy games. Gameplay is good. Nothing to cry about, and nothing to scream about. You simply point, and click.
Graphics are amazing.
The scenario and background won't let you look at the characters, for you will be too busy admiring the scenery. It's as if the Earth is sick, and the cities are huge, open wouns. Pretty sick stuff, but deffinitely eye-candy. Cop cars blown in half, corpses everywhere, huge tentacles out of the ground. Sound is, well, atmospheric, in lack of a better word.
