What the store does not explain
A current Steam discussion asks how co-op works, but its available reply does not provide a substantive, developer-confirmed answer. The evidence does not establish whether both players share every control, how pausing works, who hosts, or whether progression is saved for both players.
Treat player count as confirmed and operational details as open questions. Check the live store, patch notes, or current interface before relying on a hosting or save model.
Before starting co-op
- Make sure both players use the same current Steam build.
- Agree on civilian routing, fixed defense, and live support responsibilities.
- Test a short map before committing to a long custom scenario.
- Confirm save and host behavior in the current build.
