COO

COO, short for Covert Ornithological Operations, is a browser game by Yegor Sak where you control a robotic government pigeon drone over Toronto. It launched on November 4, 2026 with 8 covert missions, and you can ignore them to fly around, poop on pedestrians, and try to blend in.

A November 8 expansion turned it into a full 3D Toronto drawn as a living comic book, with bold ink lines, pastel cel shading, and halftone dots. Yegor says the playable area is 630 square kilometres, about nine times the GTA 5 map, with 438,819 real buildings at heights taken from the City of Toronto's 3D data and about 5,700 km of real streets you can fly over or walk. He also lists 3,237 named places with spoken facts, procedural dialogue for your handler and for pedestrians, neural voices synthesized live on your device in the browser, real-time air traffic from ADS-B, and a living city with traffic, weather, day and night cycles, and Waymos. Fast Deploy via the map jumps you to your own neighborhood.

By Yegor's account the game uses no external assets or game engine, runs on about 165,000 lines of JavaScript, and was built in 7 days by up to 10 parallel AI workstreams across 35,218 Claude model calls. He is asking Torontonians for feedback on how real the city feels. It is free to play in the browser at coo.mx.
