The hunter's map for Invader's street art. Since 1998, the anonymous French artist Invader has been secretly installing Space Invader tile mosaics in cities around the world. MapInvaders puts the complete documented catalog on an interactive map — so you can plan your hunt, track every flash, and never walk past one again. HUNT Browse 4,400+ mosaics pinned to their exact locations across 89 cities on six continents. Each piece shows its current status at a glance: active, destroyed, or already in your collection. Zoom into any street and see exactly what's around the corner. FLASH Mark pieces as you find them. Sync your FlashInvaders account via your unique UID to see your full collection overlaid on the map — green for flashed, grey for not yet, red for lost.
