From the publisher's website:
"The tide was turning in the Pacific, and the U.S. was sending a massive invasion force to the Philippines. Protecting the troop ships was the Third Fleet, and Japan saw their last best chance to win the war. The result was the largest naval battle in history, the Battle of Leyte Gulf."
"GURPS WWII: Leyte Gulf puts you in the middle of this epic battle, with roleplaying opportunities in the skies high above the dueling fleets, on deck as the shells rain down, or below the surface hunting the enemy while they hunt you. Leyte Gulf has a complete account of the battle, complete GURPS stats (Third Edition) for six warships, and GM advice for building a scenario - or a complete campaign - around the Battle of Leyte Gulf."
