Gather the listed upgrades (including Proton Torpedoes from the Core Set) and set them aside. 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 paced beyond range 1 of each other obstacle and beyond range 2 of each edge of the play area. After each obstacle is placed, place 1 cache ( Ì on it.)

After a ship overlaps an obstacle with a cache(Ì), draw 1 upgrade at random from the set-aside upgrades and equip it to that ship (ignoring its restrictions). Then remove that cache (Ì).
