Join new playable Gearloc characters Stanza and Duster as they journey down the Sibron River in search of answers in this standalone expansion/sequel to Too Many Bones! Too Many Bones: Undertow allows for 1-2 players out of the box, but by bringing in additional Gearlocs from the original game or adding in characters like Ghillie, Nugget, and Tink, you can create an adventure for up to four players. Undertow features all new baddies, encounters, tyrants, and a double-sided battle mat. Battles take place both on land and on your raft, adding even more variety and brain-bending tactics.
