Mega Blast/Round 3

Once your (or both) Mega Blast have reappeared on the screen forty Rocks will come flying out of the lava at the bottom of it; once you've fired a shot at each of them to destroy them four of them will leave three blue device packs and one red device pack behind. Once you've collected them your (or both) Mega Blast shall start moving upwards as a group of six Type 5 enemies flies towards them from the right side of the screen while firing beams at them - and once you've fired a shot at each of them to kill them, the fourth and sixth ones shall leave a green device pack and a fourth blue device pack behind. Once you've collected them, a group of six Type 2 enemies will fly down into view from the top of the screen; once you have fired a shot at each of them to kill them the sixth one will leave another red device pack behind. Once you have collected it a group of eight Type 8 enemies will fly towards you from the right side of the screen while firing projectiles at you - and once you have fired enough shots at each of these to destroy their barriers (and kill them), another group of six more Type 5 enemies will fly into view from the left side of the screen while firing beams at you. Once you have fired a shot at each of these to kill them, the seventh and tenth ones shall leave two more blue device packs behind, while the eighth and eleventh ones will leave two more red device packs behind, and the ninth and twelfth ones shall leave two more green device packs behind; once you have collected them (providing they haven't scrolled off the screen), your (or both) Mega Blast shall start moving upwards again, as twenty more Rocks come falling down and flying up into view from the top and bottom of the screen. Once you've fired a shot at all of them to destroy them, two of them shall leave two more blue device packs behind - and once you've collected them, a group of four Type 4 enemies shall fly into view from the right side of the screen while firing homing missiles (which cannot be blocked and must be avoided) at you. Once you have fired a shot at each of the Type 4 enemies to kill them the first three shall leave three more blue device packs behind while the fourth one will leave a fifth red device pack behind; once you have collected them, a third group of three more Type 5 enemies will come flying into view from the left side of the screen while firing beams at you. Once you have fired a shot at each of them to kill them, the fifteenth one will leave a sixth red device pack behind - and once you have collected it (again, providing it has not scrolled off the screen), two more groups of six more Type 5 enemies shall come flying towards you from the right side of the screen while firing beams at you. Once you fire a shot at each of them to kill them the twenty-first and twenty-seventh ones shall leave a twelfth blue device pack and a seventh red device pack behind; once you've collected them a group of six Type 1 enemies will fly towards you from the right side of the screen while firing projectiles at you. Once you fire a shot at each of them to kill them a second group of five more Type 4 enemies will come flying towards you from the right side of the screen while firing homing missiles (which again cannot be blocked and must be avoided) at you - and once you have fired a shot at each of the Type 4 enemies to kill them, your (or both) Mega Blast shall stop moving as the round's mini-boss (which is an enormous Moai) comes down into view from the top of the screen then starts hovering up and down in place while spitting groups of five metallic projectiles at you. Once you have fired enough shots at it, it will explode (and transform into an enormous brain-like creature) then start ricocheting around the screen while firing ring-lasers at you; once you've fired enough shots at it in this form, it will explode (and shrinks down into nothing). Your (or both) Mega Blast will then undergo a third dramatic increase in speed (which, once again, means a boss fight is coming, and just after you have defeated the mini-boss) as the following text appears on the screen:

'EMERGENCY! B.W. PROGRAM ACTIVATED'

TARGET :CONFIRMED

DISTANCE :H.P 48BA V.P C331

FILENAME :BLACK HOLE

WEAK POINT :? READY

The initially-invisible "Infinitely Great" (codename: Black Hole) shall then start firing ring-lasers at you; once you've fired a shot at it, it will become visible and start flying back and forth across the screen while continuing to fire ring-lasers at you, and with every subsequent hit, it will grow bigger until it is too big to move horizontally and starts hovering up and down in place, then shrinks down and retreats to the right side of the screen, but regrows again and starts warping off the bottom of the screen (and reappearing at the top of it every time it disappears). Once you have fired enough shots at it to defeat it, it shall explode and fall off the bottom of the screen - and your (or both) Mega Blast shall now fly off the right side of the screen as the text of "ROUND 3 OVER. NICE PLAY! GO TO NEXT ROUND." appears on the screen and proceed to Round 4 (which is set on the surface of an ocean, rather than in it).
