Bakutotsu Kijuutei/Gameplay

Controls

 * Joystick: Use the 8-way joystick to direct Takky (or Hommy if you're player 2) through each stage. As in the original, if you stop holding the joystick up, Takky or Hommy will float back down to the ground if they're in the air. (The two spacemen are now also always facing to the right of the screen).
 * Firing Button: Use this button to make Takky (or Hommy if you're player 2) fire their handheld guns at the enemies, or if they're in the new weapon, the Machine Gun Vessel, fire the guns on the front of it in turn. If they are hit while in the Machine Gun Vessel, it will explode and they will come out.
 * 1 or 2 Player Buttons: Push these buttons to begin a 1 or 2 player game.

Takky and Hommy (タッキー&ホッミー)
These biohazard-suit-wearing spacemen (who, you may remember, are caricatures of Namco employees), are the protagonists of the game; 1UP is "Takky" (who was 2UP's character in the original) and 2UP is "Hommy" ("Kissy" is nowhere to be seen here). As with the original game, the fact that they are named differently is a reminder that Baraduke may well have been intended to be the first game from Namco to allow two players to play simultaneously, but that honour would later go on to Sky Kid at the end of 1985 (and its sequel, Sky Kid Deluxe, was also the first game from Namco to use a Yamaha YM-2151 FM sound chip) - and they no longer have shields like they did in the original. If they happen to die, simply from being hit without the Machine Gun Vessel, they will be reprimanded by the Paccet Ojisan (see his section below) and sent back to the beginning of the stage to try it again; however, if they are hit by a boss character while in the Machine Gun Vessel, its presence will immediately be invalidated (and this also goes for the Turning Eye that will creep up on them if they don't heed the "HURRY"). ''To the left is the sprite of Takky and Hommy as they appear normally. To the right is the sprite of how they'll appear in their new weapon, the Machine Gun Vessel, when it has two and three guns on its front respectively. They will automatically start the second stage in it with two guns, and after dying.''

Paccets (パケットス)
These one-eyed aliens (who are from the original game) can often be found inside yellow capsules and being towed upwards by Pinseto (see their section below); every time one emerges from a yellow capsule, he will say "I'm your friend" (their catchphrase) and fly towards your spaceman. If your spaceman manages to touch him before he flies off the bottom of the screen, he will say "Bantu!" and begin to circle around your spaceman in a anticlockwise direction - Yellow Paccets are worth 200 points if collected, and White Paccets are worth 1000. Your spaceman will always have one White Paccet circling around him at the start of every stage given that they are immortal; however, the Yellow Paccets, much like their original game, are far from immortal. In fact, if they are hit by an enemy shot while they are circling around your spaceman, they will emit a scream of death and explode - sending their eyes flying up (and dropping down) off the bottom of the screen. If your spaceman manages to catch any eye, it is worth a single point; you will have to catch ten of them in order to restore the last figure of your score to its original value of "0". The Yellow Paccets will also add on to your score at the end of a stage - 1st: 100 pts, 2nd: 200 pts, 3rd: 500 pts, 4th: 1000 pts, 5th: 2000 pts, 6th: 4000 pts, and 7th + subsequent: 7650 pts.

Paccet Ojisan (パケット爺さん)
This walking-stick-wielding, white-moustached, one-eyed alien appears at the start of some of the 36 stages to give the players advice in the two Japanese syllabic writing systems (Hiragana, and Katakana), but you don't have to be able to read them in order to play through the stages; and if your spaceman dies as a result of being hit without the Machine Gun Vessel, he will reprimand him, and send him back to the beginning of the stage to try it again. He also appears in the centre of that virtual octagon that is on the left side of the screen in the bonus game that'll be invoked after the fourth, tenth, sixteenth, twenty-second, twenty-ninth and thirty-fifth stages - there is a maximum of a 2/8 chance of it landing on an "Extra Paccet" icon, a maximum of a 4/8 chance of it landing on a "Shot Power Up" icon , a maximum of a 1/8 chance of it landing on a "Shot Power Down" icon , and a maximum of a 1/8 chance of it landing on a "Machine Gun Vessel" icon. The right side of the screen will be taken up by his "dialogue box".
