I have started playing this agme and I am surprised by how much I am interested in this sc-fi FPS. I am also playing RSV2. You can't really compare a tactical shooter to a sc-fi FPS. The reviews were mixed, the worst from XPlay. I feel that it deserves a try, and given time, as in my case it will grow on you--as the glaive grew on Hayden Tenno's arm. It is a mix of Gears of War A button maneuvers for cover against hordes of Russian mutants and soldiers, but although the mechanics are not as refined, you will get into the combined action of shooter versus decapitator with the glaive. I believe a more reasonable number would be 8-8.5. Since I am playing both RSV2 and this game, I seem to enjoy the combined combat,Black Market for weapons, and crazy soldiers and monsters.
