In player order, players take turns choosing an obstacle and placing it into the play area until all obstacles have been placed.

• Obstacles must be placed beyond range 1 of each other obstacle and beyond range 2 of each edge of the play area.

When a ship rolls an attack die due to moving through or overlapping an asteroid or debris cloud, resolve the following (in addition to the normal effects):

• On a blank result, the ship gains 1 strain token.
• On a f result, the ship gains 1 disarm token.
