Entering a cave leaves a vulnerable window
With units selected, right-click a cave entrance. Units wait at the entrance for six seconds, then play their short entry animation before arriving on the other layer. They can still be attacked during the wait.
Hold Position or a new manual order cancels entry. An obstructed exit delays arrival until there is room. Flying units also use entrances and cannot fly over the underground abyss.
Caves are in the current desktop build. They are not included in the older itch.io browser or Windows demo.
Both maps keep running while you look elsewhere
Press F3 by default, or use the arrow beside Ping, to switch map views. This moves your camera; it does not pause the other layer or teleport your army.
Workers can build on clear cave floor, and gold gatherers can travel through entrances, mine below ground, and deliver to a surface base. Keep those routes clear.
Caves have no weather effects or weather gameplay modifiers. In full-game Elven play, underground units receive no nighttime health/vision bonus and Moon Wells gain no moonlight.
