  2. Manual map exploration (game knowledge approach)

There was no obvious text or map marker visible, so players had to rely on environmental clues such as:


Method 1 β€” Database Lookup (Intended Easier Route)

The image was originally sourced from gtaguessr.com β€” a game similar to GeoGuessr but based entirely on GTA V locations.

  2. Search for relevant terms such as: GTA Guessr Franklin road
  3. Browse the GTA Guessr database and locate the exact matching image.

  2. Explore the map while comparing environmental details to the screenshot.
  3. Pay close attention to:
    • Road curvature
    • Elevation changes
    • Surrounding landscape
    • Nearby landmarks

After careful comparison and exploration, the location can be identified as: Mariowe Drive
