Imagine a sci-fi third-person shooter! But with muscled-up smurfs!!!
So the story... You won't give a crap for it... It's just like Call of Duty, but without multiplayer. But anyway, you play as a... clone-marine-smurfy thingy in a war... Ummm... and the special thing about these guys is that they don't die. They are transported into chips which can be equipped to your weapons, which by doing so, can upgrade your weapons... duh...
The controls are good. Pretty easy to get used to. Nothing special. It's controlled like and first-person shooter on the Wii. Aim with the Wiimote, shoot with the B button. Jump with the A, etc.
The graphics are good, but not impressive and not ground-breaking. Actually, they're basically mediocre. Also, if you want to play the game, get used with the color BLUE. Because everything's blue in this game. The hills, the weapons, the CHARACTERS! Even the water.... Damn. This is smurfer than the smurfs.
In conclusion, Rogue Trooper isn't anything special. It's just your average thrid-person shooter on the Wii. It feels weird. It feels like a Disney Action Game, trying to be as manly as it could. You just can't make the Smurf as badass as Rambo. That's why the art-style is important, kids. Anyway, just rent it
