Great game, but pretty short.
The game is presented with a director telling you a briefing of each scene, and it can be a little funny, but then it get's annoying since it will be repeating a lot of the funny lines along the way. Again, playing the game over and over is pretty fun, specially when trying to reach a better score in each level. The game is pretty short, so be aware that you can probably finish the entire game in a couple of sittings.
As a game to add a little variety of your everyday shooter this game is pretty great, and i can see myself playing it again in the future. It does have multiplayer but I didn't try that feature. Get it if you have a chance.
