The Deep
Your world persists now: up to four save slots, each an underground realm that keeps every tunnel and upgrade between visits. Friends can join your expedition live and share the party log. Tap to walk, dig, and build; drill straight down, tunnel through walls, or fly on Icarus Wings; sell ore at the Depot for drill, cargo, and lantern upgrades. The deep strata hold gems, Chthonic Motherlodes, and awakened Echo Shrine pacts: socket gems at your Rune Forge, lay Chthonic Rails, advance the permanent Oaths campaign, and ascend a finished career for legacy laurels.
