Guilliman-augmented datasheets reshape Space Marines' rules

Warhammer Community previews the Codex: Space Marines datasheets ahead of pre-orders, led by Roboute Guilliman who can keep the Combat Doctrines aura active for himself and nearby allies. The article showcases new or updated units and abilities: Librarians in Phobos armour and Terminator armour gain powerful options; Sternguard Veterans receive expanded, artificer-powered shooting profiles (including Damnatus and Infernus options); Terminators gain a Hunter profile; and Fury of the First remains active in close combat. It also notes the psyker power rules and hints at broader rule updates for other Chapters, with more Space Marines previews coming tomorrow.
