Let's get the short answer out of the way: Big Walk has no classes. There are no character types, no skill trees, no stats, and no loadouts. Every walker carries everything a walker can carry, and everyone can do every puzzle.

What does exist is role-play — not in the menu, but in how groups organize themselves on the trail. The best parties naturally fall into a handful of roles, and naming them makes coordination easier.

The emergent roles

RoleWhat they doBest for
ScoutRuns ahead, marks landmarks, reports routes backLarger groups (7–12)
NavigatorOwns the Map Room and the route planGroups after the red tower
CallerDirects puzzles from a fixed viewpointAny puzzle with a chasm
CarrierMoves figures and collectibles between slotsGroups with long hauls
AnchorStays at the meeting point and coordinates by walkie-talkieGroups that split up

How to assign roles without drama

  • Let people volunteer. The Scout role attracts the runners; the Anchor role attracts the patient. Both are needed.
  • Rotate the Caller every couple of puzzles — calling is tiring, and rotating keeps everyone involved.
  • One role per person per segment. A player who is both Carrier and Caller is doing two jobs and will drop the key.

"Classes" in the wiki's sense

If you came here from a search for "Big Walk classes", the useful frame is: the class system is communication-based. The closest thing to a "tank" is the player who carries the key; the closest thing to a "healer" is the player who repeats directions until everyone is aligned. Build your party composition around that, and you'll never need a stat sheet.
