This is one of the most addictive and entertaining games to be released in the last year. It has an entertaining story that I have yet to decipher fully paired with challenging, unique gameplay. I find it to be similar to a puzzler at times with the need to plan your moves as you clear a level room by room but you can also play it completely independent of strategy and run in strong, relying on instinct and mechanical skill to blast past your enemies. Definitely worth the money, especially if you can grab it on sale. A must buy for anyone looking to experience something new.
