Everyone has their place on the food chain. It's a static reference to our predators and prey, dictating the creatures we're able to dominate, and those we would be better off avoiding. Sitting on the top of the chain, we as humans need not worry about being spontaneously eaten while simply out on a morning walk, but for the aquatic dwellers in Feeding Frenzy 2 it's a constant race to eat or be eaten, with a constantly evolving menu as every fish fills its belly and inflates itself in order to devour more and more. Morbid stuff for a casual game.
Feeding Frenzy 2 essentially works on the basis that there's always a bigger fish, and you want to be it. Gameplay is almost suffocatingly simple, boiling down to "eat what's smaller than you; avoid what's bigger" with the only change coming when you eat enough of the smaller fish that you're no longer one of them, and can then swim around chomping on everything that moves. It's basic, though undeniably enjoyable for what it is. Levels aren't particularly well balanced, and the lack of widescreen support (which means you are forced to play in a very narrow field of view) makes most deaths seem unfair, but otherwise it's a perfectly solid casual experience (if far less rewarding than I remember it being almost a decade ago upon release).
Budget priced and good for a few hours, I can recommend Feeding Frenzy 2 provided you are OK with playing what is ultimately little more than a mouse exercise. I doesn't hold up under extended play sessions, but for a few minutes a day it's a cute lesson on meaningless homicide, with some subliminal racist undertones to boot. What's not to love?
