: Mjolnir, you have new orders. Uploading new navigational coordinates, move there ASAP.
A waypoint appears on everyones' HUD, placed in the same direction the Huitzitlaotani planes exited towards.
: Wait, Mjolnir, you cannot just leave all of a sudden! Surely this can wait until we've reached the shore?
: I'm afraid it cannot. The Huits have punched through your fleet and Mjolnir is the nearest allied air unit. We need them over there immediately to engage carrier-based fighters.
: You do not need to deploy the entire squadron, do you? We would be totally defenseless!
: Mjolnir, you tell us. How are you going to play this one?
You may now commence debating what course of action to take, whether to stay and defend the Mercanans against new orders, abandon them to take care of business, or split the squad. Or, find a fourth option. Mission rewards will be affected by the decision made.
Note: for simplicity's sake, the "split the squad" option is essentially a few people dropping out of the mission to remain with the shipping. Any attack will be automatically repelled, and the Mercanans will have something to give as a show of gratitude, but there will be less people taking the fight to the carrier's planes.
