The usual 3x3 100 pts, but 8 asteroids. You can deploy them at 15 cmts from the edges. I recomend this if you are a purist gamer who do not like scenarios or variant rules. So easy to try, and it changes the scene. Large ships are more dificult to play, much "cover" +1 green and sometimes.the option to go straight and fly over a rock is tempting.
Generic pilots are a plus, 8 rocks means that sometimes your Push the Limits Hero can not do actions. Give this a try one day, the change is not so small as you can think.
Good flying !!!
