Will this be the expansion that convinces me to pick up Marathon?

"Runner hostilities suspended”

So we are basically just like, totally pivoting the game away from its core now I guess!

The core exfil part will still continue and expand. I’m under the impression that the runner hostility suspension is part of the PvE mode where there will be situations where multiple crews will be able to team up and battle almost like patrols in Destiny (though I assume it’ll be primarily during boss fights or something major within the PvE mode).

I think that's 100% only the expeditions which will be PvE. Extraction and all it's hostilities will still be there.
