"Well, uh, not like it was going to work anyways...well if anyone wants to climb down...there you go."
Well go join the others and take up a defensive position
You head to north where most of the people are and take position in corner.
Since we're making so much noise already...
Yell SURRENDER TO THE WILL OF THE PEOPLE, AND YOUR DISPOSAL SHALL BE HUMANE! very loudly. Find cover, take up defensive positions.
You scream your promises of death and join Vik with his gun toting in corner.
Take damn defensive position
Take damn defensive position
Do the same just incase, and be ready to kinetic punch something and chuck a grenade
"...Why is everyone taking cover? Did you guys see something?"
Follow their lead, I guess?
You lot gather in the corner with various weapons ready aiming at all doors in your sights.
"Huh. Watch out for the coilgun turrets!"
Poke around the room. Watch out for turrets.
While others are piling up in hedgehog position you wander around in the room. You sneak to the door on right side and very carefully peek into the next room. What you see reinforces your idea about this being an assembly hall, but for chemical weapons. For example the next room appears to have fridges, both normal and microwave ovens, piles of scientific instruments disguised as knives, forks and other cutlery. In fact, it looks very much like a kitchen there, but that's just a clever disguise! Defensive weapons must be hidden somewhere in there, just waiting for you to turn your back!
Perhaps Grits is one of them, because he just pushed you in open giving you clear view of the room. You drop low instantly.
"Looks like some kind of mess hall, I think. Wonder what happened here."
Also poke around the room. Don't stand in front of the rectangular hole yet. Instead hug the wall next to it and use a piece of mirror/something reflective to check what's on the other side.
Something reflective? You don't seem to have anything that fulfills that requirement in particular nor does anyone else. Of course you could always open your face plate, take of the helmet and use that as poor man's mirror, but that's a little bit of a bad idea. Let's see, what else you can use?
[Int: 1] Well, there's Filgres stealing peeks in front of you. You can use him.
[Dex: 3]
[Filgres dex: 2]
[Str: 3]
He doesn't notice your calculating stare on his back, mostly because he's staring in other direction. So with this advantage you give him firm push in front of the hole. It's not very strong push, because you want him to stay upright and clearly in sight of any potential automated weapons. That results him stumbling two steps forward and then dropping low on the floor.
Since he's still breathing it's probably safe to look by yourself. Yeah, it's a kitchen, geared for serving number of people.
