I need some help keeping my party alive.
Long story short, they snuck into a high security facility to steal a data-cogitator with information they need stored on it. It involved a two-day boat ride through a water pipe, though the group was able to rest and they are ready for a fight.
So, they arrived in an empty room, and a couple of our stealthier characters tried to sneak out.
Failed a silent move roll. The guard rolled very well and our assassin rolled poorly. Spent a fate point, failed again. The guard triggered the alarm.
I've already told the group that there are a little less than 150 people in this facility, though some of them are women and children, so there are about 70 fighting men. The group was given the option to surrender and stand down. So, of course, they fired at the guards.
So, to re-cap, the group is in unfamiliar territory, just decided not to surrender, is surrounded by a huge horde of well-armed and well-trained enemies, and I have no clue how to get them out of this alive. Potentially if they kill the first wave of guards, they could slip away and hide from the remaining 60 or so dudes, but we've got a huge tech-priest in our group who has an agility of 21 and no stealth skills.
On the plus side, we've got four mercenaries with us (Well, not mercenaries, but allies.) I could presumably have them help out in a non-combat way (Rather than rolling for a bunch of allies, I'll just have them 'Hold this area' or slip off and kill a number of bad guys.) That still leaves our heroes heavily outnumbered and outgunned.
Any tips?
