Attaining completion in Grand Theft Auto: San Andreas requires the completion of numerous tasks, all of which are listed below, along with links to pages explaining the tasks and how to complete them. Unlike the other games, GTA San Andreas has extra tasks that are not required for the achievement but are also available to complete, many players refers to this as "110%".
To attain completion in GTA San Andreas, the player must accomplish all of the following:
- Complete all storyline missions (End of the Line).
- Note: it is actually possible to complete the storyline without completing the casino heist strand and the Zero RC strand, but these missions must be completed as well for 100%.
