InvaderQuest - become the best Space Invaders hunter! You know those little pixel art mosaics tucked away on the walls of your city? For years they have been hiding in plain sight. InvaderQuest turns you into a hunter: spot them, plan your outings, and watch your collection grow - in Paris and in more than 80 cities around the world. FIND THEM A map shows every Invader around you. Each mosaic has its own page: a location hint and a link to photos, so you can spot even the most discreet ones. By default the map only shows what you still have to flash - no distraction, just your next target. PLAN YOUR HUNTS No more wandering at random: 1. Route - enter a start and a finish, and discover every Invader along your way. 2. Hunt - just say "I have an hour, around here", and the app builds an optimised loop to flash as many as possible in the time you have. 3. Walk alerts - get notified when you pass close to an Invader, even with the phone in your pocket and the app closed. DISCOVER THE CITY ALONG THE WAY Your routes and your hunts also take in what is worth seeing nearby: monuments, squares, gardens, artworks. More than 1,700 documented places, each with a summary of its history. The best finds are the ones you were not looking for. YOUR COLLECTION Every catch joins your Collection: its photo, its date, its points. Write a note beside each one to remember where it was, and who you were with. A grid that fills up, city by city. TRACK YOUR PROGRESS 1. Cities - your completion city by city and, in Paris, district by district. Those bars filling up are dangerously addictive. 2. Stats - your activity over time, your streaks, your records. 3. News - new Invaders, mosaics reactivated or gone, in the cities you care about. ARRIVING WITH A HISTORY? Bring in all your flashes at once from your FlashInvaders account, or from a .csv or .txt file. And you can export the whole thing again to switch phones without losing anything. BUILT FOR HUNTERS No account, no server: your flashes, your notes and your locations never leave your phone. A carefully crafted arcade style interface, in French, English, Spanish and Italian. Whether you are a Sunday stroller or a relentless collector, InvaderQuest is with you from the first mosaic to the last. The city is your playground. Now go flash them all!
