Full Steam announcements and update articles for this title.
We keep making them because you keep buying them.
This is not our fault.
The RATSHAKER™ - The Mommy Pack is out now, adding two brand new cosmetic skins and a collection of new dialogue lines for your RAT.
Abs. Power. Contempt.
She could protect you.
She won’t.
Muscle Mommy comes with her own new dialogue lines, allowing her to judge, intimidate and emotionally overpower you throughout the basement.
You paid for this one yourself, which is embarrassing, but at least she looks like she could bench press your entire Steam library.
Pearls. Lipstick. Disposable income.
You cannot afford her.
So she has paid her own way into your game.
Sugar Mommy also comes with her own new dialogue lines, delivered with all the generosity, glamour and financial irresponsibility you would expect.
She is generous.
She is glamorous.
She is enabling your worst habits.
We have also released RATSHAKER™ - THE SKIN BANQUET, a new Complete the Set bundle containing:
RATSHAKER™
The Supporter Pack
The Rat-Chan Pack
The RATSUMMER Pack
The MOMMY Pack
Because it is a Complete the Set bundle, you only pay for the items you do not already own.
Muscle Mommy has also applied an additional 30% discount.
No buffs. No bonuses. No advantages.
Just two mommies, new dialogue lines and another deeply avoidable purchase.
HAVE A RATRATRATRATRATRATRAT-TASTIC DAY!
Thanks for playing RATSHAKER™!
Keep shaking that RAT! 🐀💕

No real rats were harmed in the development of RATSHAKER™ and/or the RATSHAKER™ - The MOMMY Pack *but we were.
HEY RATSHAKERS,
The TALKING SUMMER RATSHAKER PLUSH disappears at 12PM PT today.
THAT IS JUST 12 HOURS AWAY.
He is nine inches tall.
He is shaped like a hot dog.
He talks when you squeeze him.
He contains lines like: “THEY TURNED ME INTO A MARKETABLE PLUSHIE.”

Hey RATSHAKERs,
THE RATDOG UPDATE HAS ARRIVED.
Step outside the house and find the hotdog sigil.
Stand on it.
A new hotdog-making minigame has been added outside the house.
Open the fridge.
Take the sausage.
Grill the sausage.
Summon the bun.
Prepare the tray.
RAT. DOG.
When the sausage and bun are ready, condiments will fall from the heavens and the new skin will be yours.
Ratdog has also escaped the screen.
"Nothing says summertime like a hotdog-shaped rat, or is it a rat-shaped hot dog? Either way, you probably shouldn't eat this plush, no matter how delicious it looks! At 9 inches tall, this perfectly cooked red rat that has pained face and squiggle of mustard down their belly as they're wrapped tightly in a golden brown hotdog bun. They're not just for shaking either, give this rat a big old squeeze to activate the soundbox inside to let them blurt out a few hilarious catchphrases!"
Complete the Ratdog Cookout to unlock the new RATDOG CHEF skin.
You do not need money.
You only need to complete the ritual.
The Ratdog Cookout features:

Hey RATSHAKERs,
You thought we’d stop with RAT-CHAN? No, no, no. The rot never rests, the vermin never sleep, and we are never done fixing things that should have worked in the first place.
Fixes: - All audio added in the RAT-CHAN DLC is now correctly affected by volume sliders. - RAT-CHAN dialogue is now 2x louder!
Additions:
...
NO. THIS IS NOT AN INVASION.
THEY ARE SICK.
TOO SICK TO FLY!
A TRAIL OF DESTRUCTION FOLLOWS. GRASS FLATTENED. EARTH TORN. SOMETHING LEAKING. GRAB YOUR RAT.
GO TO THE CRASH SITE.
THEY ARE NOT FROM HERE.
THEY ARE FROM SOMEWHERE WORSE.
A DIFFERENT UNIVERSE. A SNOTTIER ONE. A SHAKIER ONE.
ONE WITH FRIENDS.
The next insane experience from Sunscorched Studios.
Should you visit the crash site your RAT may see something it should not see. A new cosmetic skin for the RAT!
RADIATION, ILLNESS AND OTHER SIDE EFFECTS INCLUDED.
Look at his wobbly little antenna and glass helmet.
Don't squeeze too hard!

More than 100,000 of you have now SHAKEN and SQUEEZED you RAT, willingly or otherwise… So to celebrate this sacred RAT-milestone, and of course to wish you all a merry RAT-mas, we have unleashed a limited edition bundle containing:
A Youtooz collectable RATSHAKER Plush
A 1 year RAT-iversary A3 poster

Treat yourself. Treat your grandma. She deserves a RAT.
Keep 🐀 SHAKING, keep 👊SQUEEZING, and don’t forget to 🎮 play this month, a 🎁 PRESENT is waiting for you in the living room…

HEY RATSHAKERS,
Catch yours before they scurry into the vortex of spooky darkness and SHAKE IT, SQUEEZE IT, LOVE IT! And receive a FREE Limited Edition RATSHAKER™ Achievement Sticker A4 Sheet!
It captures the chaotic charm of the rat in full plushie form. Crafted with ultra-soft minky fabric and lovingly stuffed to be the perfect blend of cuddly and unhinged!
Whether you're proudly displaying it, stress-squeezing it, or shaking it like your life depends on it, the Youtooz RATSHAKER Plush will be sure to bring maximum comfort and a little bit of chaos to your day!
Warning: Prolonged exposure may cause an overwhelming urge to shake / squeeze objects, drain unknown meters, and induce indecipherable whispers. Side effects may be irreversible.
HEY RATSHAKERS,
ACCEPT THE INESCAPABLE MARCH OF TIME. THE RAT WAITS FOR YOU. PRE-ORDER NOW: This guarantees your claim. A mark upon the ledger. The ritual begins. T-SHIRTS ARE RELEASED IN BATCHES: A relentless cycle. A churning machine that does not sleep. The ritual is ongoing. FIRST COME, FIRST SERVED: If you hesitate, you fall behind. The RAT does not look back. It does not mourn the indecisive. WHEN YOUR SHIRT SHIPS, YOU WILL KNOW: The transmission will reach you. A signal in the dark. A whisper in the static. IT HAS BEGUN. RAT-ISFACTION GUARANTEED!
Warning: Prolonged exposure may cause an overwhelming urge to shake / squeeze objects, drain unknown meters, and induce indecipherable whispers. Side effects may be irreversible.
Hey RATSHAKERs,
Our RATgineers have clawed their way back from the VOID. They return bearing new fixes, new features and an overdue apology!
Gamepad Vibration: Your gamepad now vibrates when shaking and squeezing. The more violent the shake, the stronger the tremor. FEEL IT.
Gamepad Shaking Overhaul: We've overhauled how shaking feels on gamepad to match the console ports. Gamepad shaking input is now much more responsive at all sensitivity levels.
Generator Gamepad Support: At long last, you can activate and complete the generator shake sequence using only a gamepad. Just remember: LET GO OF THE TRIGGER when IT says STOP.
Credits Update: Our elevator credits now reflect the brilliant work of our Korean and Japanese localisation linguists.
Apologies To Our Steam Deck Shakers! We’re aware that generator shaking didn’t work properly on gamepad since launch. This forced Steam Deck users to switch to the trackpads despite the game being Steam Deck Verified. It’s fixed now. The RAT seeks your forgiveness and offers ITS most SINCERE apologies.
Make sure to restart Steam to apply this update. Thank you for playing RATSHAKER!

No real rats were harmed in the development of RATSHAKER™.
Hey RATSHAKERs,
Is simply shaking a rat for it’s own sake not enough to lift that dour rat-itude? Do you desire the thrill of rat-ical competition against other like-minded Ratshakers to feel truly content with life?
Well, I’ve got news for you! The Shake-O-Mania has begun, where every great shaker of rats can shake their way up a global leaderboard to see who alone reigns supreme.
THE LEADERBOARD
All you need to do is keep on shaking your rat. THE SHAKE-O-MANIA IS ETERNAL.
THE WINNER IS THE ONE AT THE TOP AT THE END OF THE UNIVERSE.
DISCLAIMER: it is not a competition. There is no prize, no official ranking, and no ultimate winner, not even at the end of the universe. Any references to leaders, champions, or universal dominance are purely for entertainment purposes and do not reflect actual competition outcomes or rewards. Participation does not imply skill, victory, or supremacy. It just means you’re part of something ridiculous, chaotic, and possibly very fun.

Thank you for playing RATSHAKER!
Keep shaking that RAT! 🐀

HEY RATSHAKERS,
THE RAT-POCALYPSE DRAWS NEAR.
LESS THAN 2 WEEKS REMAIN UNTIL THE RATSHAKER PLUSHIE RETURNS TO THE VOID FROM WHENCE IT CAME.
NO AMOUNT OF SHAKING WILL BRING IT BACK - AND YOU'RE ALMOST OUT OF TIME...
