It’s a dog-eat-dog world out there.

Or rather, it’s a fish-eat-fish world, something millions of gamers are well aware of after clicking through Feeding Frenzy, one of the more popular casual games to surface over the past few years.

If you’re still hungry for more, PopCap has just released Feeding Frenzy 2, a splashy sequel that adds a boatload of new features, bonus fish and a fun storyline.

In case you haven’t played the original game, the concept behind these wildly addictive games is that you play as a small fish out to fend for yourself in the dangerous oceanic waters. Your basic goal is to eat fish smaller than you (including guppies or minnows), while avoid being eaten by larger fish (such as great white sharks or giant barracudas). Eventually, you grow in size and can then eat larger fish you once swam away from, so you can become top of the food chain.

Every level also introduces new controls, such as a fast dash move (left mouse-click) or the ability to suck in fish and other items (right mouse-click), plus new predators and extra power-ups to collect such as a bonus life embedded in a bubble or a large pearl housed in a sunken treasure chest.

One of the reasons the first Feeding Frenzy caught on among players of all ages is how easy the game is to control. At first, you don’t need to press any buttons at all – instead you simply move your fish by moving the mouse around; push left and your fish moves in that direction in real-time, or pull back on the mouse and your fish dives to the ocean floor. In fact, Feeding Frenzy was one of my 3-year-old son’s first computer game…yet at the same time, I, too, enjoyed the increasingly challenging levels (as a 35-year-old!).

Feeding Frenzy 2 doesn’t stray too far from what made its 2004 predecessor a splash, but adds a wealth of new features to satiate seasoned fans and newbie players alike.

Along with the beautiful new scenery, which includes new underwater worlds, including deep sea caves and sunken ships, stunning coral reefs and even above water challenges (where you must jump up to eat flying insects, perform moves for style points and try to break your personal height record!), Feeding Frenzy 2 adds a story, new game-play elements and 20 fresh faces that will help or hinder your journey.

The lengthy story mode has players assume the role of six different kinds of fish, spread throughout 60 frenzied levels. You learn that the ocean is in a state of chaos, with some fish species missing and others out of place, and so you must uncover the cause of all of this and face the problem.

You can find and eat power-ups that grant your fish special powers, such as a lightning bolt that gives you super speed, mushrooms that shrink any nearby fish so you can eat them in one bite, shield fish that offer temporary invulnerability and an elusively quick goldfish that, when eaten, automatically boosts you up to a larger fish size. Obstacles to avoid aren’t just bigger fish – they can also be mines that explode on contact, hungry above-water pelicans and dangerous bioluminescent plankton.

Other extras include “all you can eat” bonus stages without predators, new “midnight zone” levels where you must use Edie’s glowing lure to light your way and a race-against-the-clock Time Attack mode that offers even more fun game-play aside from the lengthy main story campaign.

There’s nothing fishy about this eagerly-anticipated sequel, so be sure to download and play Feeding Frenzy 2. It’s an instant-classic, but don’t take our word for it — dive in!
