The main goal is to determine the drop rate of crimson ghosts and whether your current level affects the level of the drops (seems like it does based on replies so far).
One of the questions asks how many games of crimson doubles you have played. You can check this on guardian.gg using the following links (replace "yourpsn" with your psn or "yourgamertag" with your gamertag) :
* PS4 : http://guardian.gg/en/leaderboard/2/523/YOURPSN
* Xbox1: http://guardian.gg/en/leaderboard/1/523/YOURGAMERTAG
You can only answer the survey once. No login required to answer.
