It is more detailed, makes more sense and has a stronger ending. Four Navy SEALs are sent down to supervise this mission. Headed by Lt. Coffey, played by Michael Biehn. Too bad that Coffey suffers the effects of HPNS and begins to go a little over the edge. A U.S. submarine has just sunk under the ocean.
Russian involvement is suspected and a team of navy seals is sent down to invesitgate.
But as time goes on a storm brews above while strange events go on below. Events escalate as the mining platform runs out of life support, the seals retrieve a nuke from the sunken sub and arm it, events heat up between America and Russia above, and the so called aliens are seen. Things have to be done quickly so they can stop World War 3 and really find out what the intelligent lifeforms are. The Insectoids have destroyed most of the fleet in a cowardly sneak attack. With humanity enslaved, the last survivors of a small fleet led by War Admiral Norman North try to escape the advancing Insectoid fleets while searching for a new weapon that they can use to fight back.
