The "investigate" game mode is a place where you can help Nancy Wheeler solve strange mysteries happening in Hawkins. Assign the right characters to investigate a Mystery. Once the Characters are done with the investigation, you will receive a reward of diamonds, coins, or other currency!
Investigations require characters of specific Color and Stars to start them.
A Character cannot undertake more than 1 Investigation at a time, but you may still use characters solving mysteries in battles at the same time.
Once an Investigation has been completed, you will receive a new Mystery every 8 hours. Mysteries that have not been started will be replaced every 24 hours.
You will also receive a notification on your phone when a mystery has been solved and you are able to collect your reward.
