RATS!! has a Steam page, and you're looking at it. It's a co-op tower defense for up to four farmhands, and I'm Hamza, the one developer making it.

You're not a cursor. You're on the field: run between your towers, build them in the middle of a wave, sell the ones that turn out to be duds, and link the good ones into combos.

• Link your machines. A tar-pot wired to a brazier makes a fire lane. Two teslas on one cable make an arc wall. 10 towers, 19 combos, 36 upgrades.

• Four worlds. The granary farm, the docks (bowl a rat into the harbor and the catfish gets dinner), the sewers where the grates erupt, and a winter farm with thin ice.

• Four crowned rats. The Rat King, the Barge Queen, the Grate King and General Frost.

• Thousands of rats. More than 5,000 alive at once when four farmhands take on an INSANE wave.

• Play together. Solo, on the couch, or online through Steam, up to four players.

• RAT WARS. A 1v1 mode: practice against the Barn Bot or duel a friend online.

A free co-op demo is planned for Steam Next Fest in February 2027. Wishlist RATS!! and Steam will let you know when you can play it.

The rats squeak when they go.
