Special Investigations begin after Case 1, when you’re assigned three tasks to complete in order to unlock the next Case.
Special Investigations offer a series of Agency assignments for you to solve and in the process you complete tasks by searching for and finding specific items.
As you find items you’ll progress through the levels within Special Investigations, plus you’ll earn coins and ‘XP’ (eXperience Points), and your Energy will be refilled. When you ‘level up’ energy will be completely refilled.
There are 17 Special Investigation scenes, each of which has its own progress. You'll have three different search modes to help you:
Silhouette mode (outlined objects)
Searching for named objects in Text mode (ABC, reverse and anagram)
Good luck, Investigator, and have fun!
