Half-Life Wiki:Canon

Canon is what refers to all material deemed to be set in the final Half-Life storyline. Official does not mean canon, see for instance the Gearbox expansions, of which the canonicity is ambiguous. Also, cut content is deemed non-canon by default, even if this content does not contradict the canon material. Consider "safe" cut content canon is just speculation.
