I've just started looking through the Onslaught at Arda I Adventure Book and there is a portion of it that is left very open for the GM with not much in the way of suggestions that I noticed. So I wanted to put the question out there to see what other GMs might have gone with for this and how it seemed to go over in their group. I've referenced the specific part in the spoiler below, don't want to ruin anything for anyone that may not have had the chance to play the adventure yet.
This adventure leaves the choice of cargo on M226 to the GM. I had hoped it might have some general suggestions like weapons and supplies for the rebellion that provide X duty per Y number of them handed over but the players can select to keep some of these items.. or a Lambda shuttle that could be taken by the PCs for use later, etc...
As I said, curious to hear what other people put in there for cargo and how successful they felt it was.
