The San Andreas, Liberty City, Vice City, Manhunt I/II, Bullworth, and custom maps combined into one big map. With gang wars, shops, added (not replaced) vehicles, peds, and weapons (yes, you can modify added vehicles and buy added weapons in weapon stores) in the same style as if R* were to make an expansion for GTA: San Andreas.
A patch for Snapshot 3.3.9 which fixes a crash when the game tries to spawn a news maverick when none of the models are loaded. This was partially fixed in 3.3.9, but not completely. The issue could still occur as a result.
A patch for the 9th big update for Snapshot 3.3.
Installation: Download and install Snapshot 3, then Snapshot 3.3, and then Snapshot 3.3.9, or just install the standalone version which does not require 3.3 or Snapshot 3.
