GTA IV's main story branches at two major decision points: the deal with Dimitri Rascalov, and the Pegorino loyalty choice. Each branch reaches the same final mission but changes which characters live or die in the third act. Either branch takes the same playtime.
What 100% completion requires:
- All 200 pigeons (flying rats)
- All 30 unique stunt jumps
- All 9 random encounters
- Friend activities maxed out (Roman, Brucie, Dwayne, Packie)
- The "Cleaned the Mean Streets" minigame (clear all most-wanted criminals)
