Helldivers 2

The main benefit is everyone gets an in-game currency reward if you succeed. Nothing huge, but the equivalent of what you would normally get in 4-6 missions of normal play.

They have sometimes tied new content to major orders. For example, a few weeks ago there was an order to capture planets that were supposed to contain mechsuit manufacturing plants. When we completed the order, they released new mechsuit content. Had we failed, they probably would have written a new story line where we got them a week later.

My guess is if we fail this order, there will probably be a different set of planets that we fight on next week, but it won't really be noticeable from a gameplay perspective. Just a different set of 5 or 10 planets on the map closer to Super Earth.

Long-term, there might be a wider plan for what happens if we succeed or fail too many orders. For example, last week we succeeded in a bunch of orders against the robots so they claimed we successfully wiped them off the map and couldn't fight them anymore. Then a few days later they launched a "surprise invasion" and it basically reset the map, just on different planets.
