The Big One is one of Story Mode's hidden achievements, though its name and the timing of most unlocks line up with finishing the last big heist of the main story. At 22.8%, it sits in uncommon territory, roughly matching how many players see the story through to that point. Rockstar has not published an official requirement, so this reading comes from the achievement's placement and its name rather than a confirmed source. Either way, the percentage fits a major story achievement more than an obscure side one, well above the rarer hidden achievements tied to earlier optional content on this list. Players working toward full completion should expect this one to fall into place on its own once the story's final act is finished, rather than needing any separate attention.
This is a hidden achievement. Play through the story and it will unlock at the right moment.
Achievements unlock on Steam, PlayStation (as trophies) and Xbox alike. Cheats disable them for the session, so play clean when you are chasing one.
