There is no text chat, so people have to resort to shooting tears in a certain direction and moving around the room in order to communicate their goal. People inch towards an item, shoot a tear at a specific player, and all sorts of other attempts to create in-game communication.
Also, I had a run where someone didn’t unlock holy mantle for lost. We all died to a spike rock in the middle of a room on Downpour II. Absolute comedy.
