Explore 10 Downing Street in a brand new way...

10 Downing is a 50-page campaign for Mausritter, the epic sword-and-whiskers RPG. The campaign includes a complete setting with 11 integrated questlines and 5 ready-to-play quests that create a cohesive story throughout the location.

Purchase the A5 hardcover directly from DriveThruRPG *

For as long as the British Prime Minister has lived at 10 Downing Street, so have the mice. For many years they co-existed in peace, with only the kitchen staff knowing of their existence, leaving them tasty morsels to secret away into their homes in the walls. It was a wonderful, peaceful time.

Then the rats arrived.

A gang of cockney rats started muscling their way into the house and causing trouble for mice and humans alike. The rest of the staff discovered this rodent problem and sought to end it once and for all. Thus, a new member was added to the Prime Minister’s staff - a cat, with the grand title of Chief Mouser.

For many years, Larry, the Chief Mouser, has been happily employed and lives a pampered life with the humans. While he certainly does do his best to rid the house of rats, he holds a secret alliance with the mice - if they agree not to cause trouble, he will leave them alone. He employs a retinue of mice who serve him faithfully, mostly out of fear that the unbalanced alliance could end in disaster for them at any moment.

"10 Downing: A Mausritter Campaign includes everything a Mouse Master and her micey medley need to play through a mini-campaign of multiple mouse sessions."

- pookie @ Reviews from R'lyeh

Some things you'll find inside this campaign set in the real-world house of the British Prime Minister include a trap dungeon, a floor tile puzzle, a Home Alone-style quest where you get to set the traps, political intrigue and treachery, a stealth-based quest, sneaky opponents, and mysterious artefacts.

Like with Kiwi Acres, we really enjoyed getting to check out this adventure for Mausritter! It posed new challenges, gave us more areas to explore, and was engaging for both me as the game guider and my kid as the player. We liked the variety in the different quests available and had a lot of fun with it – I hope you do too!

How can you use this?

Introduce your players to the setting and allow them to walk around the house and find out about the residents and quests at their own pace. The quests are complete adventures that take place within the house and they can be taken on in any order the players like, with the outcomes having a real impact on the political landscape and how subsequent quests will play out.

Use the keyed map and random encounters to bring the action to your players and allow them to add their own narratives to the storied halls of 10 Downing Street.
