Once your Fighters have come flying up into view from the bottom of the screen, and the background has faded back in, two Asteroids shall fly into view from the left and right sides of the screen; once you have fired enough shots at both of them to kill them, two wormholes shall open up on the left side of the screen as four Boss Galagas, twelve Batta, two Yuubaku Mushi, eight Ei and six Amembo emerge from them, fly upwards and take their positions in the formation. Once you've fired a single shot at as many of the Batta, Yuubaku Mushi, Ei, and Amembo as you can to kill them, along with two shots at as many of the Boss Galagas as you can to kill them, any remaining enemies in the formation will start to attack your Fighters - and once you have fired a single shot at all of the remaining Batta, Yuubaku Mushi, Ei, and Amembo to kill them, and two shots at all of the remaining Boss Galagas to kill them, two groups of four more Yuubaku Mushi and ten more Amembo will fly into view from the left and right sides of the screen, and circle around while firing a hail of bullets down at you. Once you've fired off one shot at as many of them as you can to kill them, a maximum of two Yuubaku Mushi and eighteen Amembo shall fly off the left and right sides of the screen while a maximum of two more of both enemies shall fly down towards your Fighters; once you have fired a shot at each of them to kill them, four more Boss Galagas, ten more Batta, eight more Ei, four more Yuubaku Mushi and six more Amembo shall come flying down into view from the top of the screen, while firing another hail of bullets down at you, then take their places in a second formation. Once you've fired a single shot at as many of the Batta, Ei, Yuubaku Mushi and Amembo as you can to kill them (and two shots at as many of the Boss Galagas as you can to kill them), any remaining enemies in the second formation will start to attack your Fighters - and once you fire a single shot at all of the remaining Batta, Yuubaku Mushi, Ei and Amembo to kill them (and two shots at all of the remaining Boss Galagas to kill them), your Fighters will fly up off the top of the screen as the text "STAGE CLEAR!!" appears on it (they'll then proceed to the twelfth stage, which has fourteen more enemies).
Stage 12[edit]
Once your Fighters have come flying up into view from the bottom of the screen, and the background has faded back in, the text of "GALAXY ZONE" will appear on the screen; two Boss Galagas, six Ei, six Amembo and eleven Batta will then come flying down into view from the top-left corner of the screen while firing a hail of bullets down at you, and fly over to the right side of the screen.

Stage 14[edit]
Once your Fighters have come flying up into view from the bottom of the screen (and the background has faded back in again), seventeen Amembo and nineteen Batta shall come flying into view from the left and right sides of the screen, and circle around while firing a hail of bullets down at you; once you have fired off a shot at as many of them as you can to kill them, a maximum of eight of both of enemy types will fly up off the top of the screen (the other remaining enemies will take their places in the formation). Once you fire off a shot at each of them to kill them, nine more Amembo, two Yuubaku Mushi, four Boss Choucho and a twentieth Batta will come flying down into view from the top of the screen, while firing another hail of bullets down at you - and once you have fired a single shot at as many of the Amembo, Yuubaku Mushi, and Batta as you can, to kill them (and two shots at as many of the Boss Choucho as you can to kill them), a maximum of both of the Yuubaku Mushi and two of the Amembo will fly off the left and right sides of the screen (the other remaining enemies will again take their places in the formation).

Once you have fired a shot at each of them to kill them, any remaining enemies in the formation will start to attack the Fighters; once you have fired a single shot at each of the remaining Amembo and Batta to kill them (along with two shots at each of the remaining Boss Choucho to kill them), the Fighters will fly up off the top of the screen as the text "STAGE CLEAR!!" gets displayed on it (they shall then proceed onward to the fifteenth stage of the game, which is also its third "Challenging Stage").
Stage 15 (Challenging Stage)[edit]
Once your Fighters have come flying up into view from the bottom of the screen, and the background has faded back in again, the text "CHALLENGING STAGE" shall fly into view from the right side of the screen and off its left side; five Boss Tentoumushi and five Boss Galagas shall then come flying into view from the left and right sides of the screen and arrange themselves into a straight line (the formation will then rotate in a clockwise direction until it is oriented vertically and each enemy will rotate in a clockwise direction individually). Once you've fired two shots at all of them to kill them, two wormholes will open up on the left and right sides of the screen as five more Boss Tentoumushi and five more Boss Galagas emerge from them in order to arrange themselves into another straight line (the formation will then rotate in an anticlockwise direction until it is oriented horizontally as that background scrolls to the left and each enemy will rotate in a clockwise direction individually) - and once you've fired two shots at each of them to kill them, the background shall change, as eight last Boss Tentoumushi, eight Boss Choucho, and four last Boss Galagas fly into view from the screen's left side (each one of the formations will also move upwards in a clockwise direction to make room for the next one until they reach the screen's right side at which point they will fly off it). Once you fire two shots at each of them to kill them, your Fighters will fly up off the top of the screen as the text "RESULTS" flies down onto it.
In one-player mode the player's number of hits and bonus of 100 points per hit will be tabulated in the centre of the screen, and if he or she managed to kill all forty enemies, the text of "PERFECT! SPECIAL BONUS 10000 PTS" will appear below it; however, in two-player mode, both players' numbers of hits and bonuses of 100 points per hit will be tabulated on the left and right sides of the screen and the text "PERFECT! SPECIAL BONUS 10000 PTS" will appear under that of the higher one (even if that player didn't actually kill all forty enemies). The Fighters will now proceed to the Space-Plant Zone.
Note: If you do not move your Fighter or fire any shots at the enemies during this stage, the text of "LUCKY! AUDIENCE BONUS 7650 PTS" will appear below your number of hits (which will obviously be 0) and bonus (which will obviously be "NONE") at the end of it; 7650 is Namco's goroawase number.
