It's not that the game looks bad. The Turok II engine, as used in Southpark, was primarly designed for use on the N64 - which has a very limited texture capacity when compared to current PC hardware. While you wander around Southpark, it's hard not to notice that you're unable to see something in the distance. The game-engine based cut scenes look great, though one wonders why NO ONE stands still. Every single character nods back and forth, back and forth, like they drank 40 gallons of high grade coffee before the sequence was designed.
Single player is fun, to some degree, if very very repetitive.
If we somehow manage to, we come out with an FPS game not different enough to be really notable and that feels fine when controlled using a standard Quake configuration. The weapons themselves are perhaps the most amusing thing about the game, and they save Southpark's gameplay from utter and complete boredom. Each weapon possesses dual-fire capabilities, even if every type of attack is silly to an extreme. The default weapon is the snowball, which can be chucked at insane speeds against your ever-oncoming enemies, or in alternate fire, turned into a more damaging 'dirty snowball'. If you're unfamiliar with the later term.
