Legions of Steel is a tactical miniatures boardgame created by Clark Browning, Marco Pecota and Derrick Villeneuve. It simulates futuristic combat between the power-armoured U.N.E. troopers from Earth against endless numbers of robotic Nightmares, led by the dreaded Mark I Assault Fiends. Battles take place inside the labyrinthine corridors of the invading Machines' underground production facilities, which are simulated through the use of modular, interlocking tiles. Many expansions have been released detailing everything from new units to entire new factions, along with many optional rules for expanding the depth of gameplay.
