Setup: The second player places the station in the center of the setup area. Then, starting with the second player, the players alternate placing the remaining obstacles, adding 2 purrgil and 2 dust fields and excluding the asteroid fields, at distance 2-5 of the station.
After deploying fleets, each of the second player's ships gains a token.
Special Rule: Each ship can resolve the following effect:
: You may spend engineering points to gain victory tokens from 1 station or dust field at distance 1. If that obstacle is a station, gain 1 token for each 3 points you spend. If that obstacle is a dust field, gain 1 token for each 2 points you spend. Then, if that obstacle is a dust field and you gained more than 1 victory token, remove that obstacle from the play area.Victory Token: 10 pts.
