The Pacific Theater was defined by amphibious landings, beaches, lagoons, and much more.
The Hell Bent boxed expansion for Old School Tactical Vol III: Pacific 1942-45 brings you that much more with an additional 30" x 41" map, yet another sheet of counters, and a bunch of scenarios to use them with.
Include are scenarios for
Wake Island,
Tarawa (2),
Peleliu (4),
Luzon (2),
Saipan (2), and
Okinawa (3).
