Vanquish is about a grumpy nicotine-addict in a SuperSuit blasting the crap out of Soviet robots. While that may be putting it a little to simply, story isn't much of a concern to the developers of this title as you will see within the first few cutscenes. What is of a premium is cigarette smoking. There isn't one cutscene without the hero Sam Gideon lighting up a cancer stick while dodging enemy robots.
This title is all about the gameplay. Risky it may be to put the hopes of your game on how it plays alone, Vanquish really hit a home run.
