Celousco was an massively multiplayer free-to-play online browser game that Atelier 801 canceled production of. Players are split into three teams, each of which is represented by a totem animal: green (deer), blue (otter), and red (scorpion). The teams will compete in real-time for control of a fortress in the center of the map. One team will control the fortress initially, and the other two will attempt to capture it. A number of secondary objectives will be present around the fortress which can be used to weaken it. There will be a variety of map types including desert, jungle, tundra, swamp, and plains, each with its own unique characteristics. The fortress and faction bases are spawned in fixed locations, with other important places that can be used to gain a strategic advantage spread across the map. The game is expected to support as many as 2,000 players on a team, and up to 200-300 players on-screen at once. The game design was inspired by the 2001 MMORPG Dark Age of Camelot.
