"I'd describe Vigilante Justice as a 'Feature Conversion'. There are no large map changes and it mostly aims to add new features and a new style of gameplay to the existing San Andreas setting.
There are some rather large additions, including working Car Washes and a whole new inventory system. Additional weapons is something I still need help to do but if weapons are added, they won't just be like the plain old weapons you've already used with a different model, they'll have their own unique features. There are also changes to minor details at the time of writing, changes to some food vendors have taken place. Another example is slight expansion of the drug dealers AI. All of these things advance SA one step further and make gameplay more immersive.
Vigilante Justice tells the story of Officer Carl "CR" Ronson in both the past and present tense. These parts of the story link up together nicely and take place both during and after the events of San Andreas. The missions are designed to be fun, action-packed and at times, down-right hilarious. Although there are a few that are made to be detailed and immersive."
