Invader is a French urban artist. He is known for his ceramic tile mosaics modeled on the pixelated art of 1970s–1980s 8-bit video games, many of which depict the titular aliens from the 1978 arcade game Space Invaders (the inspiration for his pseudonym). As of December 2020, his creations can be seen in highly-visible locations in 79 cities in 33 countries. To accompany his citywide installations, or "Invasions", Invader publishes books and maps as guides to the locations of his mosaics.
