The strogg have capture a ship, killing all the passengers. That ship was carrying 3 Data CDs being transported by our military personnel on board, and the Data CDs are now in Strogg hands. These CDs contain vital information and must be recovered.
Your mission is to get the three Data CDs and then escape with them. To escape, you will use the submarine that will be following the ship. You will thus need to do three things: get the CDs; stop the ship, so you can jump to the submarine; and then escape on the sub. We believe to know the location of one of the CDs and you will be informed of that location when you start the mission.
