Fish Eat Fish is a fun multiplayer underwater game where the simple rule “big fish eats small fish” drives all the action. You start as a tiny fish and must eat fish smaller than you to grow, while avoiding larger fish that can eat you. The twist? Up to three players can play simultaneously on the same keyboard, turning it into a competitive local multiplayer experience.
The underwater arena is filled with fish of various sizes swimming around. Your fish grows each time you eat a smaller one, and the colour coding makes it easy to tell at a glance which fish you can eat and which to avoid. As you grow, more fish become potential prey, but the largest predators in the arena are always a threat. The balance between hunting and fleeing creates constant tension.
The 3-player mode is where Fish Eat Fish really shines. Three friends sharing one keyboard, each controlling their fish with different key sets, creates hilarious moments of betrayal and competition. You can eat each other when you’re bigger, leading to dramatic size reversals and last-second escapes. The colourful underwater graphics and simple controls make it perfect for casual gaming sessions with friends.
