Fate/Grand Order Gutentag Omen Adios (FGOGOA) is a parody Mobile game based on Fate/Grand Order, featuring artwork from Riyo. The game was launched April 1, 2018, only lasting the 24 hour period for the April Fools' Day celebration.
The game is an AR game involving pelting Servants with Saint Quartz to capture them. Differing from Fate/Grand Order Gutentag Omen in which one Servant was encountered at a time, Adios is a 3D shooter in which many copies of Servants are displayed. Clearing all the copies captures the Servant. The captured Servants can be arranged in a separate mode for screenshots.
