The tropical environment, not the music. The music, in fact, is that BA-DA-DA BA-DA-DA orchestral stuff that means ACTION is about to occur. The Sniper: Ghost Warrior trailer claims that the footage is created using the game engine, but the trailer is nevertheless FMV, presumably showing how the game is meant to be understood. You’re a sniper, you shoot people from far away. There’s a chance it will be awemazing, I suppose, depending on the craft of the long-distance shooty, but it’s being developed by City Interactive, who don’t have the very best track record with such things. Anyway, it’s looking superficially fancy, so go take a peek.
