User Summary: New Rules, New Missions is a 44-page booklet that presents a smattering of additional rules—including new "weapons" for various Conflicts, and rules for saddling up a rabbit mount—alongside a host of welcome setting material: a new patrol culled from the pages of the second Mouse Guard comic series, three new Settlements—Flintrust, Grasslake, and Sandmason—, the addition of Celanawe to Kenzie's patrol as a playable character, and three brand new exciting Missions!
