Character mods allow players to change the appearance, clothes, and sometimes the abilities of the game's characters. These mods are created by the community using various tools provided by game developers or third-party software.
If you're looking for a portable version of the game with mods, I'd recommend checking out reputable sources that offer safe and reliable downloads. Keep in mind that modifying games can sometimes lead to instability or other issues.
