Galaga '88/Stages 27-29

These are the final three stages in the game. Much like {{~|Stages 8-10 (Dimension1, 2 or 3|stages 8 through 10]], they feature a vertically scrolling challenge in which enemies and other obstacles appear. After you travel far enough into the stage, the entire formation appears all at once.  Since these are the last stages, there are no opportunities to obtain warp capsules.  The 27th stage will culminate in a fight with a boss.  Which boss you fight is determined by the dimension you encounter them in.

Stage 27
After the two Nins disappear, the screen comes to a stop. The background will rumble as the entire stage formation appears instantly. Rely on the same strategies that got you through stages 8 through 10. If you have double or triple shots, it shouldn't be too hard to thin out the formation before they start to descend. Keep moving to avoid attacks, and don't let your Fighter get pinned into a corner where it's vulnerable to enemy fire.
 * Enemies encountered:
 * 1) Four zako will fly down together in a row.  As they do, the first of many asteroids will come into view.
 * 2) Three goei will appear from the upper right corner.  Shortly after that, four more goei will appear from the upper left corner, and fly among the asteroids.
 * 3) The red asteroids which take eight shots will now fill the left and right sides of the screen, leaving only a narrow path down the middle.  At this time, a series of brown asteroids (which only need four shots) will descend down the middle.  Between sets of brown asteroids, a lone brown pan will weave back and forth down the screen.
 * 4) After the asteroids begin to clear out near the top, two Nins will attack simultaneously.

Stage 28
After the baby Dons pass, the screen will stop scrolling and the formation will come into view. All of the same strategies for the previous stage apply. Fire up at the formation as rapidly as possible while moving back and forth to draw the enemy's fire. As with all of Dimension 2, the trickiest enemies to deal with will be the Nins, so try to eliminate them as quickly as possible.
 * Enemies encountered:
 * 1) This stage starts off with a single combine Goei descending down the screen as it winds back and forth.
 * 2) As the first asteroid appears, you will be attacked by six pairs of Nins that appear one pair at a time.  More asteroids will show up and likely get in the way of your shots as you attempt to shoot each Nin three times to destroy them.  Destroy what you can, and dodge the rest.
 * 3) After the sixth pair appears, a single crystal will fall down near the left side of the screen.  This is followed by a group of baby Dons who are arranged in the shape of a zako.  It is incredibly hard to defeat all of them, even if you have a Triple Fighter and are well prepared for them, but if you manage it, you will earn 4600 bonus points.

Stage 29
At this time, the boss of Dimension 2 will appear. An oversized version of one type of Nin creature will appear at the top of the screen. It attacks much like the mini-boss you encountered in stage 10, by shooting bullets at you, as well as spawning several enemies such as zakos, goeis, Dons, Boss Galagas, and combined goeis. It takes 20 shots to defeat the boss, and you will earn 100,000 points for doing so. You will also earn 10,000 points for every remaining life you have before flying up through the top of the screen. You will then be presented with.
 * Enemies encountered:
 * 1) This stage starts immediately with four goei flying in a line down the left side, and an Amoeba moving back and forth along the right.
 * 2) Four zako will appear on the screen together in a row along with a second Amoeba.
 * 3) The next enemies to appear will be all four Nins together in a single row.  Two extra Nin will also appear right above them.
 * 4) Lastly, two combined goei will criss-cross down the screen.

Stage 27
After the asteroids pass, the screen comes to a stop. The background will rumble as the entire stage formation appears instantly. Rely on the same strategies that got you through stages 8 through 10. If you have double or triple shots, it shouldn't be too hard to thin out the formation before they start to descend. Keep moving to avoid attacks, and don't let your Fighter get pinned into a corner where it's vulnerable to enemy fire.
 * Enemies encountered:
 * 1) Two pairs of goei will appear from both top corners, and fly around the middle of the screen.  Around the same time, an Amoeba will appear and fly back and forth along the right side of the screen
 * 2) Three zako will appear, lined up in a row.  They dive down towards the bottom, and are quickly followed up by a second trio of zako.
 * 3) Four zakos fly down in a single file, as a second Amoeba appears along the left side of the screen.
 * 4) Three Boss Galagas will appear as a third Amoeba appears on the right side of the screen.  They are followed up by another trio of zako flying together in a row.
 * 5) A cluster of brown asteroids fall as a single combined goei weaves back and forth, dropping to the bottom of the screen.

Stage 28
After the baby Dons pass, the screen will stop scrolling and the formation will come into view. All of the same strategies for the previous stage apply. Fire up at the formation as rapidly as possible while moving back and forth to draw the enemy's fire. As with all of Dimension 3, the trickiest enemies to deal with will be the Pans, so try to eliminate them as quickly as possible. Don't remain beneath them as they fly down unless you are very close to popping them.
 * Enemies encountered:
 * 1) This stage starts off with two combine Goei descending down the screen as they criss-cross winding back and forth.
 * 2) As the first asteroid appears, you will be attacked by four pairs of Pans that appear one pair at a time.  More asteroids will show up and likely get in the way of your shots as you attempt to shoot each Pan four times to destroy them.  Destroy what you can, and dodge the rest.
 * 3) Before the fourth pair of Pans appears, brown asteroids will drop through the left path created by the red asteroids.  Then the fourth pair will follow behind.
 * 4) Finally, a group of baby Dons will appear arranged in the shape of a butterfly.  It is incredibly hard to defeat all of them, even if you have a Triple Fighter and are well prepared for them, but if you manage it, you will earn 5200 bonus points.

Stage 29
At this time, the boss of Dimension 3 will appear. An oversized version of the Dimension 1 zako will appear at the top of the screen. It attacks much like the mini-boss you encountered in stage 10, by shooting bullets at you, as well as spawning several enemies such as zakos, goeis, Dons, Boss Galagas, and combined goeis. It takes 20 shots to defeat the boss, and you will earn 200,000 points for doing so. You will also earn 10,000 points for every remaining life you have before flying up through the top of the screen. You will then be presented with.
 * Enemies encountered:
 * 1) This stage starts immediately with four goei flying in a line down the left side.  A field of red asteroids appears quickly after.
 * 2) As the asteroids fill in, a combine goei will glide down the screen, followed shortly by a second combined goei.
 * 3) A trio of a type of Kan will fly down the screen at this point.  Unlike their Dimension 4 counterparts, these Kan are always exposed, and never flip over to their armored side.  You earn 2200 points for each one you destroy.
 * 4) All four differently colored Pans will appear at the top of the screen and criss-cross with one another as they descend.  This attack formation repeats a second time shortly after.

Stage 27
After the baby Dons disappear, the screen comes to a stop. The background will rumble as the entire stage formation appears instantly. Rely on the same strategies that got you through stages 8 through 10. If you have double or triple shots, it shouldn't be too hard to thin out the formation before they start to descend. Keep moving to avoid attacks, and don't let your Fighter get pinned into a corner where it's vulnerable to enemy fire.
 * Enemies encountered:
 * 1) Four goei will appear single file, and fly around the middle of the screen.  Around the same time, a cluster of red asteroids will appear along the right half of the screen.
 * 2) Four zako will appear, and follow nearly the same path as the goei before them. Afterward, a series of brown asteroids will drop down along the left half of the screen.
 * 3) Four more goei will appear and follow the same path as the first set.  More red asteroids will follow, clustered more around the middle.
 * 4) A set of crystals will drop down the left side of the screen, and a combined goei will follow behind them.
 * 5) Four exposed Kans will descend from the top.  These Kans will remain exposed the whole time, and will not shield themselves from your attacks.  Each one is worth 2200 points when destroyed.
 * 6) Finally, a set of baby Dons will descend down the right side of the screen, roughly arranged in the shape of a Galaxian flagship.  It is fairly difficult to destroy all of them, but if you manage to do it, you will earn 5800 bonus points.

Stage 28
After the combined goei pass, the screen will stop scrolling and the formation will come into view. All of the same strategies for the previous stage apply. Fire up at the formation as rapidly as possible while moving back and forth to draw the enemy's fire. As with all of Dimension 4, the trickiest enemies to deal with will be the Kans. Do your best to destroy everything thing that drops down below them, and pick them off whenever they leave the formation and make themselves vulnerable to attack.
 * Enemies encountered:
 * 1) This stage starts off with four exposed Kan enemies flying down the screen in single file.  Red asteroids will also begin to appear around the middle.
 * 2) A different set of four exposed Kan enemies will fly down the screen as well.  A red asteroids will be flying around off to the right side of the screen.
 * 3) Yet another set of four exposed Kan enemies will fly down.
 * 4) An Amoeba will appear at the top of the screen.  At the same time, two pairs of zakos will swoop down to attack, criss-crossing in the middle.
 * 5) One pair of combined goei will fly down the screen, on opposites sides, followed quickly by another pair.

Stage 29
At this time, the boss of Dimension 3 will appear. An oversized version of one of the Kanso will appear at the top of the screen. It attacks much like the mini-boss you encountered in stage 10, by shooting bullets at you, as well as spawning several enemies such as zakos, goeis, Dons, Boss Galagas, and combined goeis. It takes 20 shots to defeat the boss, and you will earn 300,000 points for doing so. You will also earn 10,000 points for every remaining life you have before flying up through the top of the screen. You will then be presented with.
 * Enemies encountered:
 * 1) Four zakos will fly down from the upper right corner, lined up in a row.  A single red asteroid will also appear in the upper right corner.
 * 2) A set of brown asteroids will appear down the middle of the screen.  A trio of exposed Kans will fly down among them.  More red asteroids will appear throughout the screen.
 * 3) Three more exposed Kan will appear from the upper left corner.   They will be followed by another quartet of zakos flying together in a row.
 * 4) A mixture of all four types of Kans will fly down together, followed quickly by a single combined goei.
