Additionally, Xbox and Xbox 360 versions exist. The Windows version, Feeding Frenzy Deluxe, is available for download as a trial, with the full version available for a fee. The free ActiveX version of Feeding Frenzy can be played online at websites such as the MSN Gaming Zone, but has only a limited number of levels. The full game includes both a normal mode and a ' time attack' mode. These both end when a short period of time without further rapid consumption elapses. If the player continues to rapidly consume other fish, a further Double Frenzy can be achieved. If the player eats a sufficiently large number of fish in a short period of time, a score-enhancing Feeding Frenzy is initiated. Players must be vigilant for hazards which include depth charges, larger predators, naval mines, irradiated fish, and jellyfish. By the end of each level, the fish is sufficiently large enough that it can eat almost anything on-screen. As smaller fish are eaten, the player's own fish grows in size and becomes capable of eating somewhat larger fish.

The player takes on the role of different aquatic species each trying to move up the food chain. The last level is where they attempt to dethrone a large shark, the 'Shark King', using Orville the Orca. During the course of the game's 40 levels, they switch off between 5 marine animals. In Feeding Frenzy, players control a hungry marine predator intent on munching as many other fish as possible.
