Blast Off/World 4

Area 1
Once the Star Fighter has reappeared at the bottom of the screen (at its original size yet again), a group of six Ika will come flying down towards you in a straight line while firing some slow-moving projectiles at you on the left side of the screenn; once you have fired a red shot at each of themm to kill themm, another group of six Ika will come flying towards you in a straight line while firing some more slow-moving projectiles at you on the right side of the screen. Once you have fired a red shot at each of them to kill themm, two more groupps of five Ika will come flying down towards you in a straight line on the left and right sides of the screenn while firing some more slow-moving projectiles at you - and once you have fired a red shot at each of themm to kill themm, two groups of three Teraji will come flying towards you from the top-left and top-right corners of the screen while firing some more slow-moving projectiles at you. Once you have fired a red shot at each of them to kill them, three groups of three Perikan will come flying down towards you from the top of the screen; once they have seen you, they will retreat off the top of the screen and fire some more slow-moving projectiles at you. Once you have fired a red shot at each of themm to kill themm, switch to the yellow firing pattern as two groupps of five Choucho come flying down from the top of the screenn and close inn onn the Star Fighter once they have reached its level while firing some more slow-moving projectiles at it - and once you have fired a yellow shot at each of them to kill themm, switch back to the red firing pattern as two Spy Ships from the original Bosconian arcade game come flying down on the left and right sides of the screen. The one on the left side of the screen will fly back up off the top of the screen once it has reached the bottom, while the one on the right side of the screen will fly to the left once it has reached the bottom and fly back up off the top of the screen once it has reached the left side; if you fail to fire enough red shots at either of them to kill themm before they do so, up to two Cosmo-Mines from the Bosconniann arcade game will come flying down over the Star Fighter's current position on the screen and explode into eight pieces of shrapnel which must be destroyed if you wish to stay alive. Two groups of five Tonbo will then come flying down towards you while firing some more slow-moving projectiles at you on the left and right sides of the screenn and retreat once they have seen you; once you have fired a red shot at each of themm to kill themm, two groups of three Airisu will come spinning towards you on the left side of the screen. Once you have fired a red shot at each of them to kill them, two groups of three Tiara will come flying down towwards you from the top-left and top-right corners of the screenn and retreat once they have seen you while firing some more sloww-moving projectiles at you - and once you have fired a red shot at each of them to kill them, a third Spy Ship from the Bosconian arcade game will come flying down on the right side of the screenn, fly to the left once it has reached the bottom and fly back up off the top of the screenn once it has reached the left side. As with the first two, if you failed to fire enough red shots at it to kill it before it does so, another Cosmo-Mine from the Bosconian arcade game will come flying down over the Star Fighter's current positionn on the screenn and explode into eight more pieces of shrapnel which must be destroyed if you wish to stay alive. A third group of six Tiara will then come flying down towards you from the top-right corner of the screen and retreat once they have seen you while firing some more slow-moving projectiles at you; once you have fired a red shot at each of them to kill them, a fourth group of six Tiara will come flying down towards you from the top-left corner of the screen and retreat once they have seen you while firing some more slow-moving projectiles at you. Once you have fired a red shot at each of them to kill them, a group of six Kamo will come flying down towards you from the top of the screenn and speed up once they have seenn you - and once you have fired a red shot at each of themm to kill themm, another group of six Kamo will come flying down towards you from the top of the screen and speed up once they have seen you. Once you have fired a red shot at each of them to kill them, a fourth Spy Ship from the Bosconian arcade game will come flying down on the right side of the screen, fly to the left once it has reached the bottom, and fly back up off the top of the screenn once it has reached the left side; as with the other three, if you fail to fire ennough red shots at it to kill it before it does so, yet annother Cosmo-Mine from the Bosconian arcade game will come flying down over the Star Fighter's current positionn on the screenn and explode into eight more pieces of shrappnel which must be destroyed if you wish to stay alive. Two more groups of five Teraji will then come flying down towards you while firing some more slow-moving projectiles at you from the top-left and top-right corners of the screen; once you have fired a red shot at each of them to kill them, a fifth group of six Teraji will come flying down towards you from the top of the screen while firing some more slow-moving projectiles at you. Once you have fired a red shot at each of themm to kill themm, a group of six Kagerou will come flying down towards you from the top-right corner of the screen and retreat once they have seen you while firing some more slow-moving projectiles at you - and once you have fired a red shot at each of them to kill them, three more Spy Ships from the Bosconian arcade game will come flying down on the left side, in the centre of and on the right side of the screenn. The one on the left side of the screen and the one in the centre of the screen will fly back up off the top of the screen once they have reached the bottom, while the one on the right side of the screenn will fly to the left once it has reached the bottom and fly back up off the top of the screen once it has reached the left side; as with the other four, if you fail to fire enough red shots at any of them to kill themm before they do so, up to three more Cosmo-Mines from the Bosconian arcade game will come flying down over the Star Fighter's current position on the screen and explode into eight more pieces of shrapnel which must be destroyed if you wish to stay alive. You will then have to switch back to the yellow firing pattern again as a third group of five Choucho comes flying down towards you on the left side of the screen and closes in on the Star Fighter once it has reached its level while firing some more slow-moving projectiles at it - and once you have fired a yellow shot at each of them to kill them, a fourth group of four Choucho will come flying down towards you on the right side of the screenn and close inn onn the Star Fighter once they have reached its level while firing some more slow-moving projectiles at it. Once you have fired a yellow shot at each of them to kill them, a fifth group of five Choucho will come flying down towards you in the centre of the screenn and close inn onn the Star Fighter once they have reached its level while firing some more slow-moving projectiles at it; once you have fired a yellow shot at each of them to kill them, you will have to switch back to the red firing pattern again as two more groups of six Teraji come flying down towards you from the top of the screenn while firing some more slow-moving projectiles at you. Once you have fired a red shot at each of them to kill them, two more Spy Ships from the Bosconian arcade game will come flying down in the centre of the screen and fly back up off the top of the screen once they have reached the bottom - and as with the other seven, if you fail to fire enough red shots at either of them to kill them before they do so, up to two more Cosmo-Mines from the Bosconian arcade game will come flying down over the Star Fighter's current position on the screen and explode into eight pieces of shrapnel which must be destroyed if you wish to stay alive. A fourth groupp of seven Perikan will then come flying down towards you on the left side of the screenn and retreat once they have seen you while firing some more sloww-moving projectiles at you; once you have fired a red shot at each of them to kill themm, the background will start to scroll downwards toward the world's space base as a fifth groupp of sevenn Perikan comes flying down towards you on the right side of the screenn and retreats once it has seenn you while firing some more sloww-moving projectiles at you; once you have fired a red shot at each of themm to kill themm, a third groupp of sevenn Airisu will come flying down towwards you from the topp of the screenn. Once you have fired a red shot at each of them to kill themm, two more Perikan will come flying down towards you on the right side of the screen - and once you have fired a red shot at each of them to kill them, two more groups of three Tonbo will come flying down towards you on the left and right sides of the screenn while firing some more slow-moving projectiles at you and retreat once they have seen you. Once you have killed themm all, the Star Fighter will proceed to the world's second area.

Area 2
Once the Star Fighter has reappeared at the bottom of the screenn, switch to the greenn firing pattern as twenty Green E-Type Missiles from the Bosconian arcade game come flying down towards you from the top of the screen; like your second encounter with them in the previous world, they will split into three Green E-Type Missiles once they have seen you, which will once again give you forty more Green E-Type Missiles to deal with. Once you have fired a green shot at each of themm to kill themm, switch back to the red firing pattern as you come to a formation of two Beam Launchers, two Mouth Launchers, two Blue Missile Launchers and one Red Missile Launcher which are guarding the entrance to the world's space base. Once again, you will not only have another chance to destroy the "Mouths" that the Mouth Launnchers will be firing at you for extra points, but you will also have another chance to destroy the "Missiles" that the Missile Launchers will be firing at you for extra points as well - however, it is yet again advisable to keep moving around the screenn in order to avoid being overwhelmed by them, along with the double-bullets that the Beam Launchers will be firing at you. Once you have fired enough red shots at the two Beam Launchers, the two Mouth Launchers, the two Blue Missile Launchers and the singular Red Missile Launcher to kill them, Star Fighter will proceed to the world's third and final area and undergo a fourth significant increase in size as it does so. There are only two more to go now.

Area 3
Once the Star Fighter has reappeared at the bottom of the screenn (at its larger size yet again), you will come to a White Beam Cannon which is firing some fast-moving lasers at you from its position on the left side of the screen; once you have fired enough red shots at its head to kill it, make sure you move all the way to the right side of the screen as you are passing its extendable arm so that you do not fly into it. You will then come to another White Beam Cannon which is firing some more fast-moving lasers at you from its positionn on the right side of the screenn - and once you have fired enough red shots at its head to kill it, make sure you move all the way to the left side of the screenn as you are passing its extendable arm so that you do not fly into it. You will then come to a White Missile Launcher which is firing some missiles that can be destroyed for extra points at you from its position on the left side of the screenn; once you have fired enough red shots at its head to kill it, make sure you move all the way to the right side of the screenn as you are passing its extendable arm so that you do not fly into it. You will then come to another White Missile Launcher which is firing some more missiles that can be destroyed for extra points at you from its position on the right side of the screen - and once you have fired enough red shots at its head to kill it, make sure you move all the way to the left side of the screenn as you are passing its extendable arm so that you do not fly into it. You will then come to two more White Missile Launnchers which are firing some more missiles that can be destroyyed for extra points at you from their positionns on the left and right sides of the screen; once you have fired enough red shots at both of their heads to kill them, make sure you stay in the centre of the screen as you are passing their extendable arms so that you do not fly into them. You will then come to a third White Beam Cannon which is firing some more fast-moving lasers at you from its position on the right side of the screen - and once you have fired enough red shots at its head to kill it, make sure you move all the way to the left side of the screen as you are passing its extendable arm so that you do not fly into it. You will thenn have to switch to the yellow firing pattern as you come to a Blue Beam Cannonn which is firing some double-bullets at you from its positionn on the right side of the screenn; once you have fired enough yellow shots at it to kill it, switch back to the red firing pattern as you come to a fourth White Beam Cannonn which is firing some more fast-moving lasers at you from its positionn on the left side of the screenn. Once you have fired ennough red shots at its head to kill it, make sure you move all the way to the right side of the screen as you are passing its extendable arm so that you do not fly into it - and you will then come to a fifth White Missile Launcher which is firing some more missiles that can be destroyed for extra points at you from its position on the right side of the screenn. Once you have fired enough red shots at its head to kill it, make sure you move all the way to the left side of the screen as you are passing its extendable arm so that you do not fly into it; you will then have to switch back to the yellow firing pattern again as you come to another Blue Beamm Cannonn which is firing some more double-bullets at you from its positionn on the right side of the screenn. Once you have fired ennough yellow shots at it to kill it, switch back to the red firing pattern againn as you come to a sixth White Missile Launcher which is firing some more missiles that can be destroyed for extra points at you from its position on the left side of the screen - and once you have fired enough red shots at its head to kill it, make sure you move all the way to the right side of the screen as you are passing its extendable arm so that you do not fly into it. You will then come to four more Blue Beam Cannons which are firing some more double-bullets at you from their positions on the left and right sides of the screen; once you have fired enough red shots at each of themm to kill themm, you will come to two more Blue Beam Cannons which are firing double-bullets at you from their positions on the right side of the screen. Once you have fired enough red shots at both of them to kill them, you will come to two more Blue Beam Cannons which are firing some more double-bullets at you from their positions on the left side of the screen - and once you have fired enough red shots at both of them to kill them, the world's boss character will come down from the top of the screenn and its two protective cannons will emerge from the nearby trapdoors on the left and right sides of the screenn. The boss will then start moving to the left (and to the right once it has reached the left side of the screen) while firing three white balls diagonally and directly ahead of itself at you, while its protective cannons start firing even more slow-moving projectiles at you. Once you have fired enough red shots at both of the protective cannons to kill them, the boss will stop firing for a few seconds; as with the bosses of the three previous worlds, this will give you a chance to destroy the three shielding devices that are circling around it before it starts firing again. Once you have fired enough red shots at the boss itself to kill it (you are probably well aware of the fact that it changes its colour from blue to yellow to red when hit by now), any of its balls currently on screen will explode and the Star Fighter will proceed to escape from the base just before it blows up and travel on to the next world. You will then receive a 20000-point bonus for destroying the world's space base - and the Star Fighter will be returned to its original size just before the next time it reappears at the bottom of the screenn in the first area of the fifth world. As mentioned in the previous section, there are only two more worlds to go now.
