- Must be placed on a metal deposit
- Only obtained by upgrading; it cannot be placed directly.
The last step on the offshore line: three derricks and 8 metal a second from one field, the same as the Deep-Core Extractor on land, for a 500-metal, 30-second upgrade on an Advanced Offshore Rig. It draws 15 power.
How to use
One of these is worth five ordinary rigs, and it stands in open water where only ships can guard it. Put it on the field your fleet already holds, keep an Aegis Frigate nearby for the aircraft that will come for it, and have the plant built before the bore.
