Given the mass of ghosts around, going combing over the place for weapons if a bit iffy if you don't know where they are. I only found drugs in the ground floor.
Best weapon at parties IMO is actually the Molotovs in the garage on the ground floor. Send someone to get the pool que (ahem, quarterstaff) next to the pool table. But also send a couple gals to grab up the Molotovs... before the NPCs grab them and burn you with em.
Often I dont want that many captures. So ill pile up like 3-6 unconscious NPCs near each other and set them on fire with the molotov (SIZZLE) and having actual Deaths recorded for the mobs makes it more likely they'll surrender before you have to hit all of them.
Somewhere there's a Ball Bat and NPCs will usually find it for you. There's a Crowbar next to the molotovs but its not all that effective of a weapon (high miss chance).
Against Ghosts?
The Fire damage might help, I dunno.
I really wish Parties used the Sneaky condition so that you could at least bring a pocket las-charger or small revolver.
Actually this map is Bugged because there is no
Exit Grid.
If you roll Ghosts or Bogeymen and cant handle it you lose your gals and ship, so a player is just gonna reload the Geo save prior to it and skip the mission. Even on Supermutant mode having to play through up to possibly 10 days of Geoscape can be an okay tradeoff to keep veteran gals.
