Volcanic Caldera: Endless Mode
A separate survival operation with permanent one-time access on iOS.
Choose Endless Mode from the main menu. Volcanic Caldera is separate from campaign progression and does not require a completed campaign.
The operation has no terminal victory wave. Highest completed wave and best score measure your run. Additional deployment hubs activate over time, until all five contribute pressure. The Defense catalog is available under its ordinary research requirements.
Standard tenth-wave Command Core milestones remain map-specific and permanent. Claiming one prevents it being awarded again on a replay; it does not exhaust all future milestones in an unbounded operation.
Purchase and restoration
On iOS, Endless uses an optional, permanent one-time in-app purchase. It is not a subscription. Use Restore Purchases in the Endless purchase screen with the Apple Account that owns the purchase. The displayed App Store price is the relevant localized price.
Campaign and its story are separate from this entitlement. The fiction explains why independent production controllers can keep operating after Synthera's central mandate ends: they still require local isolation.
Read the machines that remain for the story context.
