About This Game

The gym opens at 10 PM. You have one hour to become the most ripped cat.

MUKIMUKI NYANKOS is a chaotic online party game for up to 8 players. Everyone starts as a tiny, fluffy kitten. Every machine in the gym is a minigame, every rep makes you bigger… and nothing stops you from getting absurdly, ridiculously, planet-sized buff.

Train

• Bench press, curls, squats, pull-ups, the treadmill, a giant hamster wheel, the leg press, a two-seat rowing boat, a mechanical bull and a punching bag that hits back: every machine is its own minigame.
  
• Follow the routine of the day and switch machines (muscles get used to it). And don't skip leg day: chicken legs trip over their own feet.
  
• Pose in front of the mirror to get pumped, drink shakes, take dodgy pills… as long as the anti-doping inspector doesn't catch you.

Betray your friends

• Swipe them off their machine, steal kilos from whoever wears the crown, throw them across the gym or finish them with a German suplex.
  
• Or lend a paw: spot a friend on the bench, build cat towers, run with them like a wheelbarrow… or use a cramped friend as a barbell.

Muscles without limits. Really.

• Grow from 30 kg to billions of kilos. Giants step over the machines, carry their friends on their back like a cat bus and can compress back to normal size for a super-powered comeback.
  
• Reach KAIJU size and the music changes, the floor shakes, the roof breaks and the gym has to expand into the parking lot.

A different night every time

• 25 crazy events: laser pointers, an evil Roomba, cucumber panic, a catnip rave, tuna rain, a mouse invasion, the legendary bodybuilder… and ultra-rare surprises like a tax audit or a UFO abduction.
  
• The Roulette of the Night spins two modifiers before every match: moon gravity, soapy floor, big heads, everyone starts as a kaiju…
  
• 11 game modes: Quick Match, The Season (a 30-night campaign with quotas, supplement cards with visible side effects, a shop and bosses), Pose Down Royale, Strongman, Giant Sumo, Tug of War, Leg Day, Bulk vs Cut, Cardio Hide and Seek, The Floor Is Lava and the Final Party.
  
• 3 gyms: the neon MUKIMUKI GYM, MUSCLE BEACH at sunset and the low-gravity MOON GYM.

Always something new

• Level up your gym to unlock modes, maps and events.
  
• Complete jobs, earn protein and open boxes full of ridiculous titles, meows and running trails.
  
• 41 achievements, daily streaks and a podium photo at the end of every match.

Features

• Online multiplayer for 1–8 players.
  
• Proximity voice chat.
  
• Play solo against bots (three difficulty levels).
