Here is how GTA San Andreas Remaster MOD look like
We are still waiting for the official confirmation of the news that remasters of old GTA games are in development, But that’s pretty likely because Take Two and Rockstar have started to fight against the unofficial "remasters" of these GTA games.
For some time now, there have been mods that insert city maps from previous GTA games into GTA 5. Now such mods have been banned from distribution
An example of one such mod was demonstrated a month ago, but as advanced as these mods may seem at first, they could actually create the wrong vision of an official remaster that will reportedly not run on the same engine as GTA 5 but on Unreal Engine.
This is just a mod and not official representation of how GTA San Andreas remastered will look like so keep that in mind.
