Mortal.kombat.x.repack-r.g.mechanics Version
The repack famously compressed the game from ~44GB down to ~11.5GB – 13.5GB (depending on whether you included all language dubs or just English). This is nearly a 70% reduction in file size.
One of the biggest frustrations with modern PC gaming is the necessity of running Steam, Epic, or the Microsoft Store in the background. This repack strips away the DRM middleman. Once installed, the game runs directly via an .exe file. This frees up RAM and CPU cycles, allowing the game to run smoother on low-end hardware.
When Mortal Kombat X launched on PC in April 2015, it was a disaster. Highveld Software (the porter) delivered a buggy mess with optimization issues. By the time the game was fixed with the XL update (including all DLC and balance patches), the installation folder had ballooned to nearly 44GB. Mortal.Kombat.X.Repack-R.G.Mechanics Version
For users on metered connections, 44GB is a two or three-day download. Enter R.G. Mechanics. Their repack accomplished the following:
A common myth regarding repacks is that compression degrades video quality, especially for the game's signature "X-Ray" moves and Fatalities. The repack famously compressed the game from ~44GB

Their goal is simple: Take a 40GB game and squeeze it into 15GB without removing a single frame of a cutscene or a single note of the soundtrack. For Mortal Kombat X, which originally demanded around 36GB of HDD space, the R.G. Mechanics version was a revelation for users with bandwidth caps or slow internet connections.
Many R.G. Mechanics releases offer a "selective download" feature. Do you not care about voice acting in Brazilian Portuguese or French? Don't download those language packs. Are you skipping the story mode and just want to play versus? You can often omit high-resolution movie files. This granularity is absent in official digital storefronts.
The most sought-after version of this repack is based on Mortal Kombat X: XL—which includes:
