Warhammer 40K: Space Marines - Codex (2026)

The Space Marines are Humanity’s greatest and most terrifying champions, equal to any teeming alien horde, though few in number. Their transhuman might is enhanced by arcane genetic alchemy, and they are clad in advanced power armour that makes each warrior a walking tank. Striking from burning skies with sudden fury, they slaughter their enemies amid the thunder of bolt rifles and the snarl of chainswords. In their wake they leave nothing but devastation as testament to the Emperor’s might.
