One of us currently has a total of three maps, the first of which is Skeld, the original map we released with the game in 2018, long before the recent surge in popularity. 

Mira HQ was released on August 8, 2019, and the latest map, Polus, was released in November that year a few months after that. 

Yes, it does mean that all three of our maps were released long before the blockade of the game's fame.
