Demo Update - Tutorial changes + lighting mode + hero previews

Underground Security Inc Demo · published 12 Mar 2026, 00:39 UTC

All eventsPlayers around this dateRead on Steam

A quick update to the demo. Added:

  • hero party previews: hovering over the preview shows a tooltip for the heroes of the next party so players can better plan for the next wave ahead of time

  • New lighting modes: moonlight, daylight vs dungeon (classic). Let me know which one is your favorite

Changes:

  • uncompleted task reset: at the start of the night phase, instead of losing all progress towards an uncompleted task (this felt a bit too punishing), instead only a single icon's worth of progress is lost

  • tutorial change -> the secondary faction has been changed to undead, and the tutorial steps have (hopefully) been streamlined a little bit
