In Boomer, the crew of the Corpus Christi discovers a chilling fact: a Soviet Typhoon-class nuclear missile submarine is alive and well. Worse, it has three of its missiles and their warheads.

Information presented in this module includes:

• Source material and maps for Norway and the Svalbard Archipelago.
  
• Background material on how the Soviet sub came to be trapped in the ice and on the operation undertaken to recover it.
  
• Rules for traversing the Arctic ice pack, and a discussion of the special dangers and encounters to be found there.

Boomer is the dramatic climax to the Last Submarine trilogy and brings the series to a close with a daring assault over the polar ice.
