Corebound (update 2: beta2.0)

Corebound is a world in which humanity polluted the planet so much that it became impossible to live on the surface, so people dug a whole complex of caves in a huge mountain. In addition, humanity created robots to do the work for people, and everything was fine until some kind of "infection" appeared. This was not an ordinary virus in the usual sense, it did not touch people, but attacked only robots, forcing them to exterminate each other and also attack people. Because of the infection, when a robot became infected, in addition to the fact that it became aggressive, it changed in appearance, more precisely, not its body itself, but the color of its "core" changed from blue to red. In the network of caves itself, these infected robots are very numerous, according to approximate data, there are about 99.9% of them ... which means somewhere there remains one uninfected ... one who is immune to the infection, which means it is possible that he will still give battle to aggressive infected machines ...

This is a robot that was not affected by the infection, most likely because it is immune to it, but it still affected it, giving it self-awareness. This is a spider robot (it has all the sensors that allow it to see and hear) that looks like a rectangular body on four legs that are attached to the front and back (and they look like a spider, and that's why it is a spider robot). On the sides, on both sides, there is an opening covered with transparent armored glass. In these two openings, you can see the core of the robot - it is blue.
The robot was originally designed for combat, and therefore has three weapon mounts, as well as slots for other modules (such as additional motors, grappling hooks that allow for aerial jumps, and the like; see Corebound: parts: modules for more details).
The robot's body was named "Crawler," but the robot itself doesn't even have a name, because after it left the factory as a prototype, the testers treated it coldly and indifferently, literally putting it through tests that it physically couldn't pass. Afterwards, they wrote down the report and simply wrote it off right away, throwing it in the landfill. So it lay in the Lost Scrapyard for an unknown amount of time until now, always remaining on (and perhaps all this time it was waiting for someone to come and take it away from there).

"This abandoned cave, filled with the wreckage of destroyed machines, is located at the very top of the world."
Lost scrapyard is the very top and very first layer of the caves
This layer is made up of grey caves where piles of metal and broken robots are scattered almost everywhere. There is light there, but it is dim and it is unclear where it comes from.
This place was previously used as a landfill
In this location there are such infected robots as:
Box
Springling
Scraplash
Roller
Dreadnought
secret robot:
Spectrum

"At one point, this was an active mining site. However, mining operations quickly ceased when the Infection began to spread. Even after mining ceased, the area remains filled with electrical crystals, which were once in high demand."
Crystal Quarry is the second layer of caves that goes below the Lost Scrapyard.
This layer consists of spacious shafts filled with energy crystals that are located almost everywhere and emit light that illuminates this layer. These crystals shock everything within a short distance from them.
In some places, bombs are attached to the ceiling on large chains that look like anchor mines, only larger and dark blue in color. They are very unstable and, if exposed to any force, explode in a large radius.
The following infected robots are present here:
Bubblemound
Drill
Voltstriker
Wiremaw
Lurkstrider
secret robot:
Voltheart

Originally built as a safe haven where technological advancement could flourish, Beacon City was once teeming with machines. However, once the Infection began to spread, the city quickly became very dangerous.
Beacon City is the third layer after Crystal Quarry.
This is a spacious city built by people, the houses are made in the form of pillars or otherwise myakov (hence the name of this place), but due to the large number of robots after the infection, the city became uninhabitable.
Here are the following infected robots:
Flareling
Rasp
Droneweawer
Purveyor
Orbital
