ARCHINT
A collection of Delta Green operations focused on archaeological intelligence: hidden artifacts, buried secrets, and appalling dangers left behind by the past. Agents investigate objects and sites including the Amulet of the Ai-Apa, the Brixton Shard, the Eggs of Apep, the Hunahp* Mask, and other occult threats, gathering information so others can remain unaware. It is playable with Delta Green: The Role-Playing Game.
