X7 is a group whose members are engaged in hunting mutants, their goals are similar to the goals of "Duty". Stalkers are newcomers, because of the name of this group, it is sometimes attributed to agents of "O-Consciousness", but this is not the case. Stalkers in this group are professional hunters or former scientists who have learned mutants "like the back of their fingers." Many members of this group cooperate with the "Debt", as they have almost the same goal. Nothing is known about the leader of the group, but it is known that the group's base is located somewhere in the forests between the Dump and the Dark Valley. On their basis, strict control is maintained, as is that of the "Debt". However, they say that it is still possible to get to the base, for a certain bribe.
