About 100percentguide

What this is

100percentguide is a collectible reference for open-world games. Each guide is a single page with the complete list of locations, grouped by region, that you can tick off as you play. Progress is stored in your own browser.

No account, ever

There is no sign-up, no login and no server storing your progress. Everything you tick is saved locally on your device. You can export your progress to a file at any time and import it on another device or browser. That file is yours — we never see it.

How the location data is checked

Coordinates are not copied from other guide sites. They are extracted from openly available structured sources and then checked mechanically: an automated suite cross-references independent sources, verifies that every coordinate falls inside the game world, looks for duplicates and spatial outliers, and detects coordinate-system mismatches that would shift every location at once.

Each item carries a confidence level derived from those checks rather than from anyone’s judgement. An item is only marked as confirmed by two independent sources when two genuinely unrelated sources place it in the same spot. Where a location cannot be supported by evidence, the field is left empty instead of being filled with a guess.

Corrections

If you find a location that is wrong, it is a bug and we want to know. The verification report that accompanies each data import lists the items most likely to be incorrect, and those are the first places to look.
