Fish Eat Other Fish

Chomp your way up the food chain, dodge your opponent's jaws, and become the biggest fish in this frantic two-player underwater brawl.

Here's the deal: you and a friend each pick a fish, drop into the same cramped aquarium, and start snapping up whatever fits in your mouth. The twist? Your "friend" is also growing, and sooner or later one of you looks like lunch. I've lost count of how many times I got swallowed mid-bite because I was too busy chasing a shiny minnow to check behind me. The controls are dead simple—one stick or set of keys per fish—but the strategy gets surprisingly mean. Small fish can squeeze through tight gaps to escape; big fish can block lanes and force a corner. I once spent a whole match playing as a tiny guppy, just darting in to steal food from my opponent's mouth, until I finally grew enough to turn the tables. It's the underwater equivalent of stealing fries off someone's plate, then eating their burger. The graphics are bright and cartoonish, with bubbles popping and tails flicking. There's no complex story or unlock system, but the matches are short, the rematches are instant, and the trash talk writes itself. If you've got a second player and ten minutes, this is the kind of game that ends with someone shouting 'rematch' at the screen.

Follow the game instructions

Stay near the edges when you're small—less open water means fewer ambush spots. Don't tunnel vision on one fish; keep your rival's position in the corner of your eye. If you're the bigger fish, use your size to block escape routes rather than chasing directly. Grab the glowing special food when it appears—it gives a quick growth burst that can flip the match. Try baiting your opponent into a corner by dropping a smaller fish, then strike when they commit. Claim the WASD side before your friend does; the arrow keys are for the second player.
