THIS GAME IS AWESOME!
Challenging, original, beautiful, innovating, playable. A MUST HAVE in a shooting games collection. WTH didn't I see it on a front page?
The bonuses make the game really dynamic, but it's too easy to play with the headphone bonus. Sometimes they're not so easy to find though.
Anyways, I loved the game and I'd LOVE to see more of innovating stuff like this on the portal. Keep it up, you rule!
