First off: I'm Max. If you're in my group, read no further.
Long story short, here's a summary of my last session and some fairly amusing situations that came up, which are presenting me with problems...
The general plot of the mission (Which was supposed to be a milk run after a very dangerous planetfall), was that an important dignitary's 18-19 year old son had been kidnapped, and he had called in all the favors he had as well as donating a frankly ridiculous sum to the inquisition in exchange for a team to discreetly investigate. (If anyone finds out that he has no heir, he's vulnerable to assassination attempts to steal his empire, since it would be up for grabs.) The big 'Surprise' was supposed to be that his son had run away to seek his own fortune, staging it like a kidnapping and fleeing with several of his low-life scum friends. (Who, of course, he had been forbidden from speaking with.)
Except, when they were being told the situation, one of the players wasn't paying too much attention or else just had too much meta-knowledge, assumed that the son had run away, and from that point the entire group started searching as though he was simply a runaway, and not a kidnapee. I'm not 100% sure everyone realized they had been blatantly told he was kidnapped, since nobody pursued that lead even a little bit.
They also wanted to find anyone who might know the son's criminal-scum-ish friends... But they were in a hive city of several billion, didn't know the friends' names, and didn't know where they lived. One player called it a 'GM wall' when I pointed out how bad an idea it was...
Anyways. I thought that was a little frustrating, but amusing. It gets better.
They managed to track down the son and his friends, finally, where it was essentially five people with lasguns and Guard Flak all beating up another guy. (The son had used stolen gear from his escape to arm his friends and himself. The guy had gone back on a deal and stolen gear from an assossiate of theirs.) There were 4 players, at this point: A level 5 Assassin, a fellowship level 5 Scum, a tanky level 3 Tech Priest, and an entirely lore/tech level 5 Tech Priest.
So what do they do? They have the assassin go get the car, then send the Scum in to cause a distraction and shoot someone in the head.
Without their only high-level character (Who was gone for 6 rounds getting the car,) the entire party was pretty neatly dealt with. Everyone took crit, and our lore-Tech Priest lost his face, which would have blinded him if he didn't have an optical mechadendrite. (Oh, and our Scum lost 1 point of armor to his chest.)
The only reason they didn't have to burn fate points is because the Assassin came back and threatened to turn them in to his father, sending him back to a luxurious captivity.
Their logic was apparently that they could kill the friends, knock out the son, and take him back.
Did I mention that the son has a best quality Cybernetic arm, with a built in Power Blade? And also that both of the Tech Priests wanted to cut it off because he 'Didn't deserve it'?
I'm really baffled by their decisions, and am trying to figure out ways to handle it without just beating them all up when they attack stronger enenies than them, while unprepared. I already pulled punches to keep them from a total-party-kill (Or, Total-Party-Fatepoint,) but I don't want this to happen repeatedly.
