Ran this last weekend and could definitely see myself doing again for another group down the road. It was my group's first time with mothership, so they were not prepared for a goblin to show up based on what they had heard. I ran it as a quick one shot to give them a taste, and they want more!
My crew ultimately welded doors and vents shut, then unloaded their guns on them if the goblin showed up and tried to open them.
I had added a couple first aid kits in the equipment room, and wish I hadn't. Between those and what they brought them they were able to stabilize all bleeding from stab wounds/ bites. I would have had 1-2 deaths without them.
Thanks for the fun and unexpected adventure!
