As they headed south through the domes, they came across a door that opened onto a security guard and a scientist in a room full of equipment. The guard was killed quickly, and they pointed a gun in the face of the scientist.
The scientist was not helpful in answering questions about the base. The scientist asserted he was just a guy who worked there. The room was full of environmental equipment. The equipment was the air handling and water processing of the facility.
The adventurers killed the useless scientist while Max attempted to figure out if there was an alarm switch in the equipment room. While Max tried to find the switch, they came across a large red button that while inspecting, managed to accidentally push. When Max pushed the button, the whole room came to a stop, as it ended up being the emergency stop for the equipment.
Between Zaphod and Seraphina, they figured out that the equipment could be tinkered with to reverse the flow of air and cause the base to be flooded with air from the surface of the planet, so they did that. They turned the machines back on and headed across the hall to a hydroponics setup, where they once again killed all the guards and scientists in the room.
With the air rather quickly becoming toxic, the adventurers set a trip wire bomb on the door to the equipment room, in the hope of exploding anyone who was going to try and fix the equipment. Very quickly a group of scientists, choking on the degrading air, found the trip wire and exploded themselves.
Thinking that drawing as many people to the equipment room to ambush them was the best, the adventurers sat in wait for the next group of people to come try and fix the air handler. After about 5 minutes, a group of soldiers showed up with a scientist, trying to figure out why the air was becoming bad.
The adventurers jumped out of hiding and the two groups traded fire before the adventurers were ultimately successful in killing the soldiers. One of the soldiers managed to radio to base security and an alarm started to go off. The base doors slid closed and became unresponsive. Overhead, a voice boomed about intruders and to shelter in place.
Realizing that there were likely more soldiers on the way, the group attempted to bypass the doors, with computer skill, but there was no interface at the door to access. Next Max attempted to crack the case and switch enough wires to force the locking mechanism open, but was unsuccessful. Finally, Seraphina approached with her plasma cutter and over the next 5 minutes burned through the locking mechanism releasing the door. So it went, with Seraphina burning locks until they made it to another dome.
As the adventurers entered the main room of the new dome, they heard pursuers loudly checking the domes they passed through. The soldiers sounded competent which freaked Fynn out, who immediately ran through the door Seraphina had just cut open, to the Eastern most part of the base they had ended up in.
The adventures moved to the hallway on the Eastern part of the Dome they were in and decided to wait and ambush the soldiers. As the Soldiers entered the main room of the dome and began checking doors, Max lobbed a grenade among the soldiers, which did not seem to do much more than make the soldiers mad.
Fynn used his wicked strong and armor piercing spear to skewer a locking mechanism and yelled for the others to follow him out of the hallway into the base. The group thought their fate was sealed though, as the soldiers riddled them with rocket rifle fire.
Alex dove head first into the group of soldiers with his dual needle guns and after a few seconds of bloody shooting, the soldiers in powered armor finally fell.
Badly injured and worried about what could still be in the base to fight with, the adventurers sat looking over their wounds, not sure what to do next.
