Choose a pattern from the narrowest part of the route, not only the destination. A formation that fits an open endpoint can still collapse at a doorway along the path.

Line-based formations

  • Line creates one straight horizontal line.
  • Row creates one or more rows wider than the formation is deep.
  • Column creates one or more columns deeper than the formation is wide.
  • Echelon creates a diagonal formation.
  • Skirmisher creates a randomly spread line.

Shape-based formations

  • Wedge places the leader at the front of an inverted V.
  • V places the leader at the back of a V.
  • Diamond places two side members around the leader and extends additional members in a trailing file or offset pairs.
  • Triangle and Square distribute members along their perimeters.
  • Grid balances rows and columns.
  • Circle surrounds the center.
  • Arc places members along an open curve.

Directional shapes are relative to the leader. Smooth abrupt turns or change formation only after the group has room to rotate.

Dynamic formation

Swarm keeps the group in a compact moving cluster rather than a rigid geometric layout. Use it when local cohesion matters more than stable role slots.

Select a formation for the route

  • Use Column for corridors and doors.
  • Use Line or Skirmisher for open lateral coverage.
  • Use Row or Grid for predictable larger groups.
  • Use Echelon, Wedge, or V when travel direction should be obvious.
  • Use Circle or Arc around a point only when the whole radius is navigable.
  • Use Diamond for a small squad with trailing members, or Triangle and Square for perimeter arrangements. Use Grid for filled ranks.

Test every group size used by spawning or pooling. Closed shapes and final rows can distribute remaining members differently from the full ideal arrangement.
