What do you mean by a card for scenarios? Something like the Missions in first edition?

I know at one point months ago people had something like scenario cards where each player would have an asymmetric goal (e.g. one player is protecting a space station, and the other player is trying to get through mines to attack and destroy it). I forget if that was late first edition or early second edition.

I took therm card from another post from 1st edition, I recall. All I am interested in are 2nd edition scenarios in whatever form. I just designed a scenario just like the one you describe. I was looking for point values for a space station- in my case a small defense outpost that is part of a picket defense. I have play tested it twice and the defense went from way underpowered to way overpowered. The attached was pointed out at 50 points and now 65 points. Since it can't move its an easy target and how to trade that for increased power and balance is not clear.
