The primary mission sequence is a core and essential portion of all S.T.A.L.K.E.R. games. Many items, quests and areas will not be available to the player unless certain primary missions are completed. Primary missions often have multiple steps towards the final goal as well as 'hidden' side quests which the player only becomes aware of when entering an area for the first time.
