It's over when I'm done wasting my time watching Chaika and actually bother to write up a proper "the bads exploded you are winner congratulate" thing.
But yes that would conclude the mission.
Oh hey episode 9's over TIME TO WRITE A PROPER ENDING.
make things go boom boom
yes
"[Coordinates received, captain. Looks like Mjolnir wants us to fire again.]"
"[Works for me. ALL CANNONS-]"
The Mach-class artillery pieces all adjust to the proper firing positions, barrels unlocking.
"[FIRE!]"
The four large cannons begin to fire, barrels kicking back violently and dragging some smoke and steam with it. The empty casings are ejected into the ground behind, trailing with vapor from the shots. With a clang and a clatter they land, skittering across the floor much in the same way that casings from a smaller round would, albeit slower and much heavier.
Twenty more shells are hurled into the air, suddenly slamming into the retreating armor column. Blast after violent blast rains down on the targets, tearing into the remaining elements of the column, and turning the ground into the equivalent of Swiss cheese.
As the last shots are fired from the Mach-classes, their barrels lock back into their idle position, scathing hot to the touch. The massive chamber plates on each lock down, and small covers unlock, revealing a series of small holes placed at various intervals along the barrel. Steam violently ejects from these holes harmlessly, the water vapor rising away from the artillery position.
Nothing remains of the armor column. No further enemy advancement is detected.
Mission success.
