Upcoming content

“I have a lot more content planned. I don't like to talk numbers because I always plan more than I can complete and then reduce the scope to something (semi-) realistic. But to give you some idea, there will be about 2 more urban locations in the Lower Underrail (where SGS is), about 2-3 urban locations in the Upper Underrail and also a couple of locations in the Deep Caverns; and of course bunch of in between areas, some dungeons, mini-dungeons and other stuff that comes with it.”

This was before Rail Crossing, Foundry and Core City were added to Lower Underrail.

Secured and secret areas

Underrail rewards exploration and perceptive characters. There are secured and secret areas to be accessed all around. Finding these yields an experience bonus in addition to the loot and other benefits. Noticing secret areas often requires a high detection, which is derived from perception. The feat Snooping helps discovering secrets without high perception.
