*JJ: Tobidase Daisakusen Part II* serves as the high-octane sequel to the game Western audiences know as *The 3-D Battles of WorldRunner*. Developed by Square before they pivoted almost exclusively to RPGs, this title pushes the Famicom hardware to its absolute limits with a blistering pseudo-3D rail-shooting engine. While the original game felt like a whimsical stroll through a surrealist landscape, *JJ* leans heavily into a gritty sci-fi aesthetic, replacing the bright colors with dark, neon-streaked environments that demand lightning-fast reflexes. The fan translation is essential for navigating the minimal menus and understanding the increased depth in power-ups, making this "lost" sequel finally accessible to English-speaking retro enthusiasts.
The gameplay loop remains focused on forward-scrolling evasion and shooting, but the difficulty has been significantly spiked compared to its predecessor. Players control JJ, a jetpack-clad hero who must navigate treacherous pits and blast through waves of robotic sentinels while managing a limited fuel supply. The standout feature remains the optional "3D" mode, designed for use with the Famicom 3D System liquid crystal shutter glasses, which creates a genuine sense of depth that was revolutionary for 1987. Even without the glasses, the sense of speed is exhilarating, though the flickering sprites and chaotic enemy patterns can occasionally lead to frustrating deaths that require strict memorization to overcome.
Visually, the game is a masterclass in NES sprite scaling and parallax scrolling, showcasing Hironobu Sakaguchi’s early directorial ambition. The soundtrack, composed by Nobuo Uematsu, provides a driving electronic backdrop that perfectly complements the frantic pace of the action. While it lacks the narrative depth of later Square masterpieces, *JJ* is a fascinating historical artifact that demonstrates the developer's technical prowess in the action genre before the *Final Fantasy* era. It is a punishing, often unforgiving experience, but for those who mastered *WorldRunner*, this translated sequel offers a definitive and more complex challenge that remains one of the most technically impressive shooters on the 8-bit platform.
