Build your own mechs from scavenged scrap and head out to adventure in a sandbox setting based on a declining British high street. As the pickings get slimmer, the vermin get more creative. Make friends and enemies from the many different factions in the market. Recycle your trashed mech parts with Reece, the Fox Merchant, dodge robot cleaners in the City of Pound and gossip with the Flock, who see all and know all.
Mechritter is a supplement for the Mausritter tabletop-roleplaying game designed to turn your game into city-dwelling, mech-battling roleplaying. Its interactive, sticker based character sheet system makes it ideal for all ages.
Don’t own Mausritter? Mechritter also comes with an SRD skeleton which makes it playable as a standalone module.
Mechritter is a modular system and sandbox setting for Mausritter. It uses the pre-existing inventory skeleton to build different mech pieces, which can be swapped out with each other to create fully custom mechs. These aren't tanky steel behemoths, they're crafty little things made of litter. The pilots belong to the squabbling factions scrapping for survival on the rapidly changing high street.
A colourful, sticker-based, mech-making engine friendly for all ages, which will allow you to build, break, repair and swap out each individual piece.
5+ factions based out of shops' walls, floorboards and other hiding places
A busy high street full of shoppers full of trash to salvage for mech parts.
Multiple missions to earn favour with factions. Will you get the gangs on the same page or be thrown into all out fighting?
Escalating events as the neighborhood keeps changing, threatening all the vermin
Mech play is simple and straightforward. Mech pieces don’t fundamentally change the Mausritter combat system, instead, they simply offer more variety, creative utility options and a bit of survivability. A mech piece could offer a simple bonus, like a bonus on saves, or a more complicated one like resistance to falling, or additional damage to the environment. Creative players may build a different mech for every mission; provided they have the resources of course.
You build a mech by sticking stickers onto your character sheet. The game comes with multiple sticker sheets, for example the office, tourist shop and restaurant sets, which you can mix-and-match between.
Mech pieces always break before the mouse inside does. The cost of failing a combat is running away with your mech shattered and your tail between your legs.
When your mech breaks, simply peel the sticker off or scribble it out. You’ll be playing with a half-functional mech until you can buy a new piece or recycle an old one, courtesy of Reece the Fox Merchant.
Mechritter is set in a large city, loosely inspired by the boroughs of London, UK. Your mice live amongst the other vermin of the city on a high street which is very quickly transforming. The gentrified coffee shops opening up don’t dispose of their waste in the old places. The local cash-and-carries and pound stores are closing down. The entry of robot-cleaners, automatic doors and pest-repelling alarms all make the high street a more hostile place for a mouse than it used to be. The only thing to do is innovate back.
As you explore the high street, you’ll meet and form relationships with the main factions you share the city with.
The Blinged Mice steal scrap from the jewelry exchange to hold their mechs together. Their love of shiny things drove a wedge between them and the other mech piloting clique: The Skeleton Keys, daring warriors plotting from their nest in the locksmiths.
The Junk Foodies, connoisseur of crumbs based out of a chain restaurant, have had their routines disrupted by extended opening hours.
The paranoid Lab Rat Pack who command the City of Pound are considering shuttering their gates until the heat dies down.
The Flock might have ruled the market for years but construction is making them anxious. Outcasts trade messages and secrets across all groups. The bird song warns of shattered peace and changing faces.
The book is an A5-sized hardcover. Printed in full colour with bright, glossy pages, the book is hardcover to make it more resistant to spills and easy to carry around to play everywhere.
All physical purchases come with postcard-size character sheets and five sticker sets designed by Yanahn.
The sticker sets are full mech bodies designed to be swapped in and out. The sticker sets which come with the original game include:
London Tourist Trash
Park Trash and Supplies
Restaurant
Office Supplies
Sewing and Crafts
Additional sticker sets can be purchased as add ons, and will be added as stretch goals to the game.
Wantsomething to store all your pieces in? Pledge at the Deluxe tier for a custom box to store your stickers. The box will feature Kaptain and his lantern, impressed with gold foil on the lid.
Like this but imagine the foiling looks a million times better.
Let’s be honest; the project is complicated enough. Sticker sheets, character sheets, and a hardcover? And a box? Honestly, what else could we add as stretch goals.
However, for every £500 over our original target up to £10k, we will add a new sticker sheet to the pack, designed by either Gustavo or Yanahn. Post £10k, keep posted for more sticker sheet stretch goals.
Shipping will be charged when the books and playsets are ready to ship. We expect to deliver the project in Summer 2026.
Approximate prices at today's rates:

USA Tariffs
For backers from the USA who are concerned about tariffs, we will find a US shipping partner should the project be successful. That means we take care of the import duties when we send the products to our fulfilment partner. However, there is a possibility that shipping will be slightly more expensive for you due to the cost of paying an additional fulfillment partner. As we plan to print books in the UK, which has a very low comparative tariff rate at this moment in time, things should be fine.
VAT and import duties
Books are zero-rated for VAT in the UK, and many EU countries have gone in the same direction. Books may still incur VAT or import duties depending on where you live. Backers are responsible for import taxes.
Everything in this game is made by real people. We don’t involve AI. Why would we bother? AI doesn't live where we live. It can’t possibly remember the 100% accuracy psychic on Lewisham High Street, or the fox we saw digging through trash last night. That’s all us.
