How does she achieve that?
This is the #1 most essential mod. It optimizes how assets are loaded into RAM, significantly reducing memory usage.
Compressing a 10GB game down to 500MB requires a 20:1 compression ratio. Standard lossless algorithms (like LZMA2 or Zstd) used in legitimate repacks cannot achieve this without stripping the game of its core assets.

Compressing a 4 GB game down to 500 MB (an 8:1 ratio) is technically extreme. In the world of unofficial "repacks," such claims usually come with heavy trade-offs or hidden dangers:
Cities: Skylines is one of the most beloved city-building simulation games of all time. However, its massive scale comes with a matching storage footprint. The base game requires around 4GB to 10GB of space, while a fully modded setup with DLCs can easily exceed 50GB.
Reduces file size by permanently deleting unnoticeable data. This is heavily used for audio and video files. Why 500MB is Mathematically Unlikely Before discussing file sizes, it helps to understand
Extreme compression often leads to CRC errors (corrupt data), meaning the game might crash once your city reaches a certain population.
Cities: Skylines relies heavily on complex assets, simulations, and graphics. Attempting to force a 5GB+ game into 500MB usually breaks the game's core functionality.
Officially, the base version of requires at least 4 GB of available storage space . While some players reported initial Steam download sizes as low as 1.5 GB to 2.7 GB due to Steam's internal compression, the installed footprint quickly expands as the game files are unpacked. Base Game: ~4 GB to 5 GB installed. With All DLCs: Can reach 12.7 GB or more. How does she achieve that
A massive jump to 60 GB required storage. Why "500MB Highly Compressed" is Often a Red Flag
The highly compressed 500MB version of Cities: Skylines is a modified version of the game that has been optimized for smaller file size and reduced system requirements. Some of the key features of this version include:
The highly compressed version of Cities: Skylines has several implications for the gaming community:
