Ordinance Heist is a new economic layer.
I'm starting to see what Bungie is doing here.
With the CARRI system they made a special section in the store for encouraging corporation, finishing contracts, helping others and exfiltrating.
With Vault Breaker they did the same thing. But this time the store have different items you can only use in that mode, and the currency exist to encourage you to progress and get to the end boss.
Now with UESC manifests, you are encouraged to hunt UESC for prestige salvage and special weapons.
I wonder if they have in game mechanic incentives in store for the remaining factions?
I could see them making an alien currency for hunting aliens (if they ever introduce organic enemies) for Nucal, and obviously some currency for killing runners if they do the same for Arrachne.
Each faction would have their own special in game rewards and special store. So maybe one week you need special upgrades, so you have to go hunt commanders, and another week you may need implants or weapons so you go hunt players.
It's pretty smart.
