After the player returns from the factory he is offered to join the Â«DutyÂ» group. The group members believe they are supposed to protect the world from invasion of the mutants. They eliminate the nidi and hives of the beasts and consider themselves witch and vampire hunters. The player joins the group. Now his protective suite is of dark-gray colour and bears a group symbol. The group mates tell him about dark stalkers and two other groups, â€œSinâ€ and â€œLibertyâ€. They give him an assignment to get to the swamp and eliminate â€œPhantasmâ€, an unusual mutant capable of controlling phantoms.
