"There is something more powerful than each of us, a combination of our efforts, a Great Chain of industry that unites us. But it is only when we struggle in our own interest that the chain pulls society in the right direction..." - Andrew Ryan
Monadnock was a service for harried parents in Rapture looking for a quick getaway. It functioned both as a travel and babysitting agency. It could be reached via its phone number 2-1104.

Though the business is never encountered during the events of BioShock, advertisements for it can be seen around the city. Neon signs promoting the shop can be seen on buildings during Jack's descent into the city via Bathysphere. Later on, in Apollo Square, the same marquee can be seen in the transit tunnel to Hestia Chambers.
