This pictures is unfortunately just as clear as the rumours about 6th, 6.5th or 7th edition of 40k, which will be out on the 24th or 31st of May and will or won’t have army lists governed by percentages or force organisation charts or both. It will also have an Eldar vs Astro Milatarum Imperial Guard or Blood Angel vs Ork box set. It may also contain the rules but not the missions from escalation.
Regardless of the fog of war surrounding the next 40k rule book this Dark Eldar Army looks quite nice to those who understand it.
