F/A/Round 4

Once your two chosen aircraft have reappeared on the screen, they will start moving forward yet again as they come to eight 501 Fourlegs that are firing projectiles up at them from their positions in the centre of the screen; once you've dropped a bomb on each of them to kill them, eight Type 2 Air Wolves will come flying down towards you from the top of the screen while firing projectiles at you.

Once you've dropped a single bomb on both of the Green Boosters to kill them (and enough bombs on the Type 3 Super Tank to kill it), another Type 3 Super Tank will come rolling into view from the right side of the screen, while firing projectiles up at you - and once you have dropped enough bombs on it, to kill it, twenty-four more Type 2 Air Wolves will come flying down into view from the top of the screen, while firing projectiles at you.

Once you have fired a shot at each of them to kill them, two more Yellow Tanks will come rolling into view from the left side of the screen while firing projectiles up at you; once you've dropped a bomb on both of them to kill them, twenty-two more Type 2 Air Wolves will come flying down into view from the top of the screen while firing projectiles at you.

Once you have dropped a bomb on both of them to kill them, four more Yellow Tanks will come rolling into view from the right side of the screen, while firing projectiles up at you; once you drop a bomb on each of them to kill them, you'll come to two more 501 Fourlegs that are firing projectiles up at you from their positions on another rock on the right side of the screen.

Once you drop a bomb on both of them to kill them you'll come to five more 501 Fourlegs that are firing projectiles at you from their positions in the centre of the screen - and once you have dropped a bomb upon each of them to kill them you will come to Power Station, which is the only static boss in the game and shares its name with the third boss from Ordyne. It will attack by firing projectiles at you from its sixteen small corner-mounted cannons; once you have dropped a bomb on each of the cannons, to destroy them, you will have to drop a seventeenth bomb upon the central reactor (which will automatically be flashing red) to destroy it.

Once you have done so it will explode - and the text "ROUND 4 CLEAR" will now appear on the screen as you receive 2000 bonus points for every group of Green (and Blue) Soldiers you'd picked up during the round. Now it is onto the fifth round, which again starts in a similar way to this one, and your two chosen aircraft must yet again rescue groups of Soldiers, but they will fight the game's third ground-based boss Hyper Cannon at its end.
