WARHAMMER 40,000 : FORGEBANE (COMING SOON)
Regular price$160.00
In Forgebane, two venerable empires clash for supremacy on a forge world that was revealed to be a tomb world following the opening of the Cicatrix Maledictum. In the boxed set, you’ll find two armies, along with rules for playing them and a new chapter in the lore of Warhammer 40,000, as the Adeptus Mechanicus discover the secrets of blackstone – a mysterious material with the potential to neutralise the powers of Chaos or even amplify it to a horrific degree.
Whether you’re just getting started and looking for a way into the 41st Millennium, curious to start an Adeptus Mechanicus or Necrons army, or just want to pick up some new units to ally with your existing force, Forgebane is for you.
The Necron Cryptek is the first to be made of plastic and features a nifty new piece of wargear that allows them to skim above the battlefield and repair your units.
Meanwhile, Knight Armiger Warglaives are a new, lightweight class of Imperial Knight, piloted by Knights in training, lesser members of noble households or just commoners with an uncanny knack for mechanised warfare. It’s the job of these smaller Knights to range ahead of their brethren and annihilate any threats – in particular, shearing through enemy vehicles or tank-hunters with the thermal spear and reaper chain-cleaver.
