How open are the side doors, can O'Connor see in?
Door, singular. Front doors, plural. Side door, singular
Very open, the goons had to open it pretty far to draw a bead on you last round, and absorbing two actions worth of assault rifle fire means it will not close properly ever again, even if it could be pulled to, which would take effort considering the top hinge is gone.
You can't see much inside the room, the lights are off. Just what I told you in the IC post.
If O'Connor has stopped firing, Clem will make her way down next to the door, chuck her grenade in and keep her foot in the door's arc so that the occupants can't easily close the door.
Acrobatic Landing 〜 Agility 7 + Athletics Group 2 - Difficulty 2: 7d6t5 1 close call but no glitches. So I'll edge reroll misses. Edge Reroll: 6d6t5 2 So that's 3 hits altogether.
Save the edge, one hit is sufficient You will be able to reach the door at the end of your turn, so chucking the grenade will have to be your third action. Necro hasn't stated whether 1 action worth of suppressive fire is all he will do.
How would I deal with shooting at the points on the hatch I have seen?
As normal, they can't dodge
You will basically work your damage against the barrier rating to blow the mechanism off.
