Hello everyone,
At the end of the Hypersonic contest we will do the same as we did for the CodeBusters contest as it greatly improved the ranking stability.
In a nutshell, once all battles have completed we will relaunch a series of 200 matches for the legend players (limited to the first 150 players).
