Rock'n 4 (Japan, prototype)

Rock'n 4 is a challenging Japanese arcade rhythm game. Players control a character (possibly a rocker, a musician, etc.) that moves to the rhythm of the music. The main objective is to complete the stages by pressing the correct buttons or performing the correct actions at the right time, usually arrows or musical instrument icons. The difficulty increases with each stage, requiring players to have quick reflexes and good rhythm-keeping skills.

The game may include various game modes, such as story mode, free mode, or versus mode. In story mode, players can unlock new songs, new characters, and new costumes. In free mode, players can choose any song they want to play. Versus mode allows players to compete against each other to see who can achieve a higher score.

Besides pressing buttons at the right time, Rock'n 4 may incorporate other elements into the gameplay, such as musical sections that require players to perform more complex actions, or stages with high accuracy requirements. The music in the game will surely be vibrant and diverse, including various genres to suit the preferences of many players. The game's graphics may be 2D or 3D depending on the prototype version. Success in the game depends on the player's reflexes, rhythm-keeping skills, and concentration.
