What makes Field Investigations different?

A Case File documents. An Investigation connects.

Field Investigators can launch a larger research question and invite the community to help answer it. Gumshoes can discover relevant Case Files across Hellios and propose them as supporting material, turning individual observations into a connected body of research.

Each Investigation can also contain multiple breakout discussion boards, allowing contributors to pursue different evidence streams without losing the larger question.
