Queen of Champions II

Queen of Champions II is a boxing sports fighting video game for the Nintendo Entertainment System (NES). Years later, worldwide releases of the game were rebranded as Queen of Champions 2 Part of the Queen of Champions series, it is a port of both the Queen of Champions and Queen of Champions DX arcade games with some variations.

Gameplay
Queen of Champions II features a boxer known as Ayumi Miyamoto, fighting her way up through ranks of the Euro Boxing Association. After facing a series of colourful fictional opponents in three circuits, the goal is to win a final "Dream Fight" against a highly skilled boxer named Ms. Dream.

Ayumi has a limited repertoire compared to most of her opponents. her punches are limited to left and right jabs, left and right body blows, and a powerful uppercut. The uppercut can only be used once the player earns a star, which is typically accomplished by counter-punching the opponent directly before or after certain attacks are launched. The player can acquire up to three stars. To perform the uppercut, the player needs to press the start button once a star is earned. To defend, Ayumi can dodge left or right, duck, and block punches by putting up his guard.

Ayumi also has a heart counter, which decreases upon being hit, blocking a punch, or throwing a punch that the opponent dodges or blocks. When the counter decreases to zero, Ayumi temporarily turns pink and appears exhausted, leaving the player unable to attack but still able to dodge, duck, and block. At this point, Ayumi can regain some hearts (and her normal color palette) only by avoiding the opponent's punches. She immediately loses all of her hearts upon being knocked down, but can regain some by getting up.

A bout can end by knockout (KO), if a fighter is unable to get up within ten seconds after being knocked down; by technical knockout (TKO), if a fighter is knocked down three times in one round; or by decision, if the bout lasts three full rounds without a clear winner. In order to win by decision, the player must accumulate higher than a certain point total by punching the opponent and/or knocking him down; the needed total varies from one boxer to the next. However, some bouts cannot be won in this manner and will automatically result in a loss for the player if the opponent is not knocked out. Ayumi can only get up three times during any one bout; if he is knocked down a fourth cumulative time, he will be unable to rise and thus lose by knockout.

When Ayumi loses her first bout to a ranked opponent, she will have a chance to fight a rematch. However, if she loses a Title Bout, she will fall in the rankings – one place for the Minor or Major Circuits, two places for the World Circuit. Losing a rematch causes her to fall one place (unless she is already at the bottom of his circuit), forcing her to fight his way back up. A third loss (not necessarily a consecutive one), or a loss in the Dream Fight, ends the game.
