Red team (bossing) on the left, yellow team (clearing 1) in the middle, and another red team (clearing 2) on the right.
Turn 1: Clearing 1 goes top-left. Clearing 2 goes top-left. Bossing goes top-left.
Turn 2: Clearing 1 goes top-left. Clearing 2 goes top-right. Bossing goes top-right to the drone.
Turn 3: Clearing 1 goes top-left and attacks. Clearing 2 goes top-left. Bossing swaps with clearing 1 then goes top-left and attacks.
Turn 4: Clearing 1 goes bottom-left. Bossing goes to top-right and as a result, clearing 2 will be returned to rightmost starting point. Clearing 2 then goes top-left, returning clearing 1 to leftmost starting point.
Turn 5: Clearing 1 goes bottom-left and take the gift box. Clearing 2 goes left and attacks. Bossing goes top-left into boss, ending the mission with (hopefully) all the objectives accomplished.
