In other words, no. As far as the story goes, a "special" research team is checking out a crashed UFO, and "special" troops are dispatched when the thing inevitably spawns some crazy critters. Nothing generic about that special story at all. The graphics seem okay (especially that hope-raising intro video), but the whole thing is a little jerky and the corridors might become too repetitive.
Still, waiting on a hands-on experience to judge its merit, because developing a smooth, fluid FPS for the DS is hard enough as it is before even thinking about decent design.
