1. General Game Overview

The game shows a top-down view of two boxers, one white and one black. When close enough, a boxer, can punch the opponent, causing them to take a step back, and a short stun duration. When in range, executing a short punch "power punch", scores two points a long punch scores one point. There are no knockdowns or rounds. A match is completed either when a player lands 50 punches or two minutes have elapsed. After the two minute mark, a decision is made in favor of the boxer that landed the most punches. Ties are possible. Two boxers are always in front of each other and they can only move up, down, forward and backwards.

The game-play is simple but there are certain techniques that a skilled player could leverage to their advantage, such as getting a player on the ropes and juggling them between punches.

1. Game Play Details for Core 1-Player Version

Objectives and Rules

Upon launching the program, a splash screen is displayed and the user has the option to select one of the options of the 1-player or 2-player version. Once the mode is selected, a boxing ring appears on the screen. The white boxer is standing stationary in the top left corner of the ring just as the black boxer stands at the opposite corner of him. The game commences after an initial count down, and buzzer. \ **DING**.

Scoring

When a player's boxing character has lined up one of their boxing gloves to the opposing player's head and presses the punch key (assigned attack button) with good timing, the program will calculate the distance between the two boxers and determine the necessary punch in order to make contact with the opposing player's head, whether that be a long or short punch. The program itself will determine whether to punch with the right or left hand. If a short punch can make contact with the opposing player's head, that option will be chosen in order to score the player the most amount of points.

Winning/Losing

A winner is chosen one of two ways. Before a set timer (2 minutes is common) runs out, a boxer achieves a score of 50 points using any combination of long and short punches. The timer runs out and the boxer that has achieved the highest score is chosen as the winner. In this case, it is possible for their to be a tie.

Hypothetical Gaming Session

Source: https://strategywiki.org/wiki/Boxing

Boxing is played in one, two-minute round against the computer or another player. During that time, you score points by hitting your opponent's head. You can achieve a KO at 100 points, or else the player with the highest score at the end of the round is the winner (a tie is also possible). Hitting your opponent's hands does not count for points, and should be used by you as a blocking mechanism.

When throwing punches you need to take into consideration the distance to your opponent and how your fist is lining up with his head. If you are in too close your punches will be ineffective, and if you are too far away, you'll miss. You'll also need to move up or down to line your punch up with the opponent's head, rather than hitting his gloves, which has no effect.
