A rich mine of VK has been discovered in the subzero wastes of Antarctica, and its direct access to the sea makes it a dangerous new focal point of the war. As the Axis forces fortify their defenses on the icy shores, the Allies plan a swift and daring amphibious assault in the hopes of claiming the enemy position. Who will gain control of this bountiful energy source and the waterways necessary to transport it? And what will this mean for the outcome of the war? It will take monumental courage to defend your prize, or heavy casualties to take it. Prepare for fierce amphibious landings on the frozen tundra of Antarctica… this is Operation Cyclone.
Operation Cyclone is an exciting new campaign expansion for Dust Tactics, the tactical miniatures board game of explosive battlefield combat. Coming later this winter, Operation Cyclone brings the fight from Antarctica’s frozen waterways to its icy shores. With an exciting scenario guide including eight new battles, as well as the supplemental rules for artillery, amphibious assaults, and more, Operation Cyclone includes everything you need to expand your Dust Tactics experience.. Also included in Operation Cyclone are six new terrain tiles, four ammo crates, four tank traps, nine terrain squares, and two amazing new heroes.
