How to Use the Interactive Map

The Interactive Map both shows the location of key points on the map, and doubles as a collectible checker.

1. Click an icon on the right side to show all the pins of a specific type, or click the magnifying glass button to search for a specific pin by name.
2. Click a pin on the map to see its name and description, and a relevant picture or video if available.
3. From here, click Mark as Acquired to indicate that you've gotten a collectible already. This will change its icon on the map to show that it has been collected, and add 1 to that pin type's Counter.
4. To undo this, click on the same pin and click Restore to unclaimed.
5. To check how many pins you have marked so far, check the Counter in the bottom left, and click the icon that looks like a checklist to see counters for all pin types.
6. If the collected pins start to get in the way, you can hide them all by clicking the green Show Pins button on the left side.
