it is a plnet called necromunda and your squad were sent to go stop the necrons but yoir squad kept disappearing, there voice are now but distant echos, screams of the past fill the haunted hall of the tomb world, anyway you can be and fraction you want amd you encounter a omagon a member of the alpha legion but yoi think its just a illusion but whem you do find him amd kill him its just your teamate and then he shows up and he bonks you on the head, now your alone im the necrom world amd you must escape before they escape, good luck (sorry for poor spelling)
