The old crew what happened and is going to happen to them.

So in Moon they were left destroying Earth and promising to Revenge to Richtofen as well as Group 935.

Time has passed and decades have gone by until Richtofen and Maxis get to contact with survivors, who they try to manipulate to achieve their own goals. Now why didn't they use the old crew? There is few reasons for that.

1. Trust: The crew would not do anything for Richtofen so they are as good as dead for him. Also would they listen to Maxis who blew up the Earth?

2. Location: They are in Moon and only Richtofen is able to teleport survivors. And he is only trying to get them killed.

3. Time: By the time of events of Black Ops 2 zombies its safe to say the crew is dead. Yes this might be shocking but don't worry recarniation is the key.

Now to the future of the crew. What has Maxis left and what are his motives. Only thing left in his life is his little girl Samantha. Its pretty safe to say Maxis is trying to get her back alive and in the process probably the old crew too.

There is few things he might use:

1. Time travel: Go back to the time they are alive and change the course of events.

2. Vril-energy: Same as the Vr-11 weapon and how Richtofen always revives the new crew to do his task. Some how Maxis could try to harness that power to himself.

Option 1 is a possibility. The original WaW maps were included in Rezzurection DLC for BO1, and we played as Tank, Nikolai, Richtofen, and Takeo in them, maybe explaining why they were at Shi No Numa and Der Riese a second time, clearly noted by the fact of some new radios and easter eggs that were in the BO1 versions of the maps that were not present in the WaW version.

Perhaps they were sent back in time to those maps by way of teleportation. (The intro to Die Rise makes most of the time travel in the story make sense now since we clearly see a flash of light supposedly warping the new crew from the supposed location of Green Run to the location of Die Rise-Great Leap Forward...)
