About Phatastrophe
Welcome to Phatastrophe — where the pond has gone completely off the rails.
Phatastrophe is a chaotic action roguelike packed with heavily armed Phrogs, explosive Chrabs, deadly Phlais and an increasingly ridiculous arsenal of weapons.
Choose your fighter, grab whatever you can get your webbed hands on and dive into relentless battles against swarms of enemies, bizarre creatures and outrageous bosses. Every run throws new weapons, abilities and combinations at you, letting you turn your character into anything from a rapid-firing gunslinger to a katana-wielding menace, elemental death machine or walking artillery platform.
And surviving the hordes is only the beginning.
Take the chaos online with friends in co-op, fight other players in competitive multiplayer, jump into a growing collection of frantic party mini-games, or pledge yourself to the Phrogs, Chrabs or Phlais and fight for control of the pond in the ongoing weekly Pond War.
Earn Scrap, unlock new characters and skins, discover weapons, master different builds and build up your collection as you play. Whether you're chasing the perfect rogue-like run, battling for your faction, climbing the competitive ranks or just causing absolute carnage with friends, there's always something else to unlock, master or blow up.
FEATURES
- Chaotic rogue-like combat – Battle escalating hordes and increasingly dangerous bosses.
- A ridiculous arsenal – Pistols, shotguns, SMGs, bows, crossbows, explosives, rocket launchers, melee weapons, elemental gear and plenty more.
- Build your own monster – Combine weapons, abilities and upgrades to create wildly different builds every run.
- Online CO-OP – Survive the Phatastrophe with friends.
- Competitive multiplayer – Fight other players and prove who's really at the top of the food chain.

- Party modes and mini-games – When surviving isn't enough, settle things with a collection of completely unnecessary amphibian sports and competitive nonsense.

This isn't just a catastrophe, it's a full blown Phatastrophe.
