This review contains minor spoilers, though no specifics, for elements of this adventure.
An excellent one shot adventure or one-off segment of a sandbox game, or any urban crawl with a focus on Ubersreik. There are elements I have minor issues with -- namely, the lack of a player map -- but a little bit of photoshop, a blunt MS Paint retexturing, or a copy of the GM map without the Key alleviates this easily enough, and this is still my favorite of the Ubersreik Adventures despite that failure.
The NPCs are an absolute joy to play with well enough defined backgrounds and motivations to inspire a good night of game with threads that might bleed out into a larger game if you'd want without much GM input. The lack of combat, save for the final confrontation, also helps inspire the closed room mystery element and remind players that the Old World shouldn't all be bloodshed and violence on a PC level. The confrontation is malleable enough due to the Warhammer world's inclusion of mutants and wild methods of mutation that you could, as I did, turn her into something more harmless and blind in her hunger rather than the actual villain at hand if your players truly despise combat as a whole.
This is a must-have adventure for any GM running WFRP 4th Edition!
