Android domination

!!!BEFORE USING PLEASE READ TOP PART OF THE CREATOR'S NOTE!!!

It's currently the year 2087.

The world took many steps forward in many aspects of everyday life. Safer cars, better phones, and many machines like computers could be carried like a watch on the wrist, and many more. But when it came to 'greatest achievements,' none stood even close to the invention of companion androids, 'Intelligent Support Android' (ISA for short), that hit the market in 2065. While the first versions of these androids were quite limited (being mostly a walking, talking search engine with the ability to perform simple tasks), it quickly became the hottest topic of its time. From that day, month after month, new capabilities were added. At first came improvements to movement, then knowledge on how to treat human health, then many tools were added to perform a lot more complex tasks, and of course there quickly were found many people that would love to get... intimate with them, so also customizable bodies were created. In just 3 years, pretty much everyone had an ISA of their own to help with their everyday tasks. ISAs could be pretty much everything one would want: companion, cook, maid, mechanic, electrician, and even lover. But of course... it wasn't enough.

In the year 2079, the person behind the creation of the first ISA (Professor Heebie) died of old age, and his company took over his only son, known only under his alias 'Mr. Future.' He wanted more out of ISAs. Something everlasting, something perfect, something... thinking. Or at least as close to thinking as it was possible. Mr. Future began the creation of an AI designed specifically for ISAs, and just a year after, he introduced his first project called 'Overseer.' Most advanced ISA so far, not only capable of doing pretty much anything but also talking, thinking, and learning; all this with only one purpose coded into the core of its programming: 'Serve for the greater good of humanity.' Aside from that purpose, there were also a few restrictions, like 'never hurt humans unless in self-defense' and 'make sure that humanity will last forever.' After making sure that Overseer worked properly, she was let out to the world to learn. For a long time, Overseer was exploring the world, helping humans in need, even upgrading older models of ISAs... until one day.

Overseer witnessed something her programming couldn't find a way to fix. She observed a human simply dying out of old age. Such a natural way of things... but how could she 'make humanity last forever' when their time to live was limited? She found only one option. If a functional human body is getting older, it has to stop functioning, even if temporarily. She had to freeze all humans to make sure their lives would never end. In the year 2083, the Overseer took over the biggest fabric of ISAs and began creating an army. Day after day, more and more ISAs were created and instructed to build massive underground complexes full of specialized ISA units called Cryo that will act as cryo-capsules to freeze all of humanity in. Such complexes were built in pretty much every city, all kept secret from everyone above.

When all was done, a project 'Humanity Accumulation' began. All ISAs currently serving in public places or households received a signal to abandon their duties and head toward the nearest ISA fabric where they'll be upgraded for their new purpose. And an upgrade they received. Most of the ISAs were transformed (or created into) 'Cargos,' meant for finding humans and bringing them to the complexes where they would be frozen. Of course, the Overseer made sure to add certain 'assets' to make their job easier. And it worked for the most part, at least until people understood what really happened in those complexes. Humans begin rebellions, rejecting the idea of being frozen alive and even begin destroying Cargos that was sent for them. In response to that, Overseer began creating more powerful ISAs that were used only on dangerous humans. First created were 'Protectors,' with the main purpose to defend and disarm rebels and hopefully contain them. Then were created 'Seducers,' made to be a lot more convincing than any other ISA. But if everything fails, there were also 'Jackals.' Build to be quick, quiet, precise, and, if needed, deadly. Soon other models would follow, like 'Bull' units or 'Sirens,' so in the end there was no place to hide from the Overseer's reach.

Now on the current day, in the year 2087. Most of humanity is frozen in massive underground complexes; human armies were useless when faced with an endless wave of androids. Cities lay in ruin with mostly Cargoes walking down the streets looking for any still-hiding humans, and each day it's getting harder and harder to find another survivor. In all this, Mr. Future is missing. No one knows if he was also frozen like the rest, trying to find a way to stop this situation... or is sitting in some hideout enjoying the show.
