Bubble Bobble is an arcade game by Taito, first released in 1986 and later ported to numerous home computers and game consoles. The game, starring the twin Bubble Dragons Bub (Bubblun) and Bob (Bobblun), is an action-platform game in which players travel through one hundred different stages, blowing and bursting bubbles, dodging enemies and collecting a variety of items. The game became very popular and led to a long series of sequels and spin-offs. The main goal of the game is to rescue Bub and Bob's girlfriends from the Cave of Monsters. It is an early example of a game with multiple endings, which depend on the player's performance and discovery of secrets.
'Baron Von Blubba' has kidnapped the brothers' Bubby and Bobby girlfriends and turned the brothers into Bubble Dragons, Bub and Bob. Bub and Bob have to finish 100 levels in the Cave of Monsters in order to rescue them.
In the game, each player controls one of the two dragons. The player can move along platforms, as well as jump to those above and to the side, similar to most platform games. Each level is limited to a single screen, with no scrolling.
The player can also blow bubbles. These can trap enemies, who are defeated if the bubble is then burst by the player's spiny back. Bubbles that contain enemies can be popped at the same time resulting in different foods being projected around the level. Each enemy trapped in a bubble equates to a different food. Food is consumed and transferred to points (an increasing scale of 1000 points is awarded for each enemy burst in tandem with another meaning: one enemy burst equals one food item worth 1000 points, two enemies burst equals two food items worth 1000 and 2000 points, three enemies burst equals three food items worth 1000, 2000 and 4000 points, and so on), which results in earning lives. These same bubbles also float for a time before bursting, and can be jumped on, allowing access to otherwise inaccessible areas. Players progress to the next level once all enemies on the current level are defeated.
Enemies turn 'angry' — becoming pink-colored and moving faster — if they are the last enemy remaining, escape from a bubble after being left too long or a certain amount of time has been spent on the current level. A monster will also become angry if either player collects a skull (the only negative item in the game), and the monster is hit by the resulting comet crossing the screen (however, this is a rare occurrence).
After a further time limit expires, an additional invincible enemy appears for each player, actively chasing them using only vertical and horizontal movements. These do not need to be defeated to complete the level, and disappear once a player's life is lost.
Contact with enemies and their projectiles (rocks, lasers, fireballs, etc.) results in death.
On level 100 you face the final boss, the 'Super Drunk' (an enlarged version of one of the games monsters the 'Drunk'). It has to be defeated by catching a 'Lightning Potion' that allows you to shoot lightning bubbles and in turn burst them to deal damage to the boss.
The game was one of the first video games to feature multiple endings. If the player completes the game in single player mode, they will get the 'Bad ending', with the remark: 'Try again with your friend'. If it is finished with two players, they get the 'Good' ending, where the brothers are changed back and reunited with their girlfriends. Also a code is revealed that has to be deciphered that enables 'Super' mode. 'Super' mode is enabled by inputting a special code (Start - jump - Bubble - Left - Right - Jump - Start - Right) at the title screen. On the US version it can be accessed directly from the title screen. 'Super mode' is effectively a faster and more difficult version of the game. Completed in 'Super' mode with two players, on top of the results of the 'Good' ending, the players get the 'True' ending, in which it turns out that the final boss of level one-hundred, the Super Drunk, was Bub and Bob's parents under a spell. They are released and everyone lives happily ever after (at least until the events of Rainbow Islands)
