OK, finally got my chance to start the Fate of the Urquan intro session.
Two players showed up. One was an "aspiring mad scientist" who had some sort of nanites that could deconstruct/build stuff as an Aspect, the other was a cyborg ninja delivery guy, with a cyber cat sidekick. Except that in the intro both were 12 year olds; so instead of nanites he had some sort of flying legos that kept running out of batteries, and the other guy wasn't a cyborg yet but he had a Tamagotchi tied to a remote control car.
They lived in the improvised colony of Unzervalt, and attended school. They were the oldest kids (the colony was only 12 years old also). I used the history school class to give some background exposition, then one of their classmates called "Jimmy Proton" (maybe not his real name), who looked and acted essentially like a more annoying version of Kyle's cousin from South Park, told them he had found a cave into the wossname research project (underground vault where kids weren't allowed) but that a huge monster scared him off, and he ran away. But only he knew the "coordinates" to the cave, and needed their help.
They haggled about what share of the "treasure" each would get. This was basically throwing larger and larger numbers which had no semblance to percentages, so they all agreed to sneak out of school. Mr. Mad Scientist Wannabe tried to use his "nanobots" to hack the teachers holo-projector, but they ran out of energy before reaching it (his skills were focused in biotech and not hacking or electronics or whatevs). So the Cat Kid (he hadn't thought of a name yet) tried to use his cat to pick up the nanobots (jury-rigging a sort of "snow plow" attachment from a ruler and some rubber bands using Robotics), but they made too much noise, the teacher noticed, asked who was doing so much racket, and they used Deceived to pin it on other kid, which made the teacher take him to the detention room or wossname.
With the way clear, they snuck out of the classroom, went with Jimmy to the mountain side (right where the guarded checkpoint or door to the archeological site), and he basically searched all on the side of the mountain trying to find the cave. In the end they arrived to a part of the wall with a very conspicuous cardboard sheet covering something. "I camouflaged it!".
They wanted to ditch him, but he said only he knew "the password" to get in. So they went in, and arrived to a medium sized cavern. The password was another piece of cardboard with a keypad drawn on it with magic marker, so they tore it down.
They were ambushed by three of some kind of porcupine-rabbits (the "huge monsters", really about the size of a labrador). One of them backstabbed Jimmy with a quill, and he fell face down on the floor yelling "agh, my allergies".
This started a conflict, with the kids using improvised weapons (cat guy had a "sword" made from circuit boards glued to a stick, the other threw rocks). First one went down almost immediately, then Mad kid started throwing rocks to another one, hitting it in the eye. So the critter got mad, picked up the rock with his fluffy paws and threw it back dealing some decent damage.
This went on for a couple more exchanges, until finally the critters went down or fled. They treated Jimmy with his medication (Mad had to search his pack and use Biotech to find out what meds to use, he ended up mixing a bunch of them. Fun stuff) He didn't feel so well so decided to go back home.
They kept going until they reached a huge cavern, they had to climb down but managed to make it easier by using notice to find a safer path, athletics to go down, using a jump rope to tie to each other. The cavern was full of scientists, there was ancient construction all over the place, and there were makeshift buildings all over (even on the cavern walls) made by the colonists.
They keep sneaking around reaching a tent where they spied a Professor Jules Farnsworth trying to hack into a Precursor AI computer (a sort of block of metal that changed between different shapes such as D&D dice), and moaning that he made no progress in the decade he had been trying.
The PCs found a small generator outside, they moved a few switches and made the lights and equipment in the tent short out. He ran out angry trying to find the "tech" that kept doing that joke on him, and they got inside.
Immediately, the computer started "playing" with them by changing shape, with the cyber cat, to the nanites, and asking if they wanted to play chess or Global Thermonuclear War on a screen that formed on the surface.
While they were distrated, the Professor returned and caught them, but rather than being mad kept asking how they did that. The computer asked if they wanted to "initialize" with a Windows yes/no dialog and he said "YES DO IT!" so the kids complied.
After this was mostly a long cutscene, where there was a sort of Earthquake, lots of robots started emerging and scaring people and knocking off buildings and picking crates of stuff. Long story short: professor was yelled at and threatened by Captain Burton, the de facto leader of the colony. In the end, she calmed down, saw that the robots were building something, Farnsworth took credit, let the kids come and go as they wanted to secretly help him with the AI, and 8 years later the construction stopped and made a half-completed but huge Precursor Tug. (pretty much the events of the videogame's manual intro).
This is more or less where we left it, so next session it's going to be Adult PCs and their adventures, In Space.
