Critical Message from Central Naval Command
Surface Battle Watch
Prestory: Operation Signal LanternAt 0417 local, Central Naval Command lost clean surface picture in a crowded littoral corridor. Merchant traffic, storm clutter, and hostile emitters are all bleeding into the same band. This terminal now carries the watch. The glowing contacts are intercepted Signal Stories; each one is a report waiting for confirmation. Sweep the display, identify the return, then lock the contact before opening the file.
1. Watch the rotating sweep for hostile returns.
2. Hover a red diamond to reveal the intercepted report.
3. Click once to lock the contact, then click again to open it.
4. Move the ship with WASD or arrow keys. Open sector view to redeploy.
