1986 年由 Namco 在紅白機（FC）平台推出的《超級鐵板陣：加索布之謎》，是經典縱向捲軸射擊遊戲《鐵板陣》的延伸與強化版本。它在保留原作精準射擊手感的基礎上，加入當時相當罕見的「解謎式關卡設計」，也因此成為一款評價兩極、極具爭議的作品。

延續系列世界觀，駕駛戰機 Solvalou，在對抗神秘敵對勢力的戰爭中深入敵陣，目標是揭開隱藏於關卡中的「加索布之謎」，並最終擊敗幕後核心存在 Gump。然而，遊戲的敘事非常簡潔，劇情主要仍以關卡推進與環境呈現為主，幾乎沒有傳統 RPG 式的故事演出。

在玩法設計上，最大的特點是「隱藏條件通關機制」。玩家不再只是單純擊破敵人抵達關底，而是必須在關卡中滿足特定條件，例如摧毀特定目標、在特定路線飛行，甚至有時需要刻意避免攻擊某些物件。如果條件未達成，在抵達關卡末端時會被特殊機制強制送回起點，形成所謂的「關卡循環」，使遊戲難度大幅提升。

這種設計讓《加索布之謎》與傳統射擊遊戲產生明顯分歧。原本強調反應與走位的縱向射擊玩法，被加入類似解謎與探索的元素，除操作技巧外，還必須透過觀察與試錯來理解關卡規則，才能真正推進進度。

戰鬥系統方面，本作仍保留系列標誌性的雙重攻擊機制：對空的主砲與對地的炸彈系統，同時也加入了一些強化道具，使火力表現更具變化。關卡場景相比前作更加多樣化，包含雲海、火山地形與機械要塞等視覺風格，在當時 FC 平台上具有相當的表現力。

在市場評價方面，呈現明顯的兩極反應。部分玩家與硬核射擊遊戲愛好者認為，它成功將射擊遊戲提升到需要思考的層次，是一種創新的嘗試；但也有大量玩家批評其解謎條件過於隱晦，缺乏提示，導致遊戲容易陷入「反覆重玩同一關卡」的挫折循環。

整體而言，《超級鐵板陣：加索布之謎》更像是 Namco 在早期對「射擊遊戲可能性」的一次實驗。它打破了純動作反應導向的框架，試圖將解謎與關卡設計融合進射擊類型之中。雖然這種設計並未成為後續主流，但在 1980 年代中後期的遊戲進化史上，仍然具有相當重要的實驗意義。

Released in 1986 by Namco on the Family Computer (FC), Super Xevious: Gump no Nazo is an enhanced sequel to the classic vertical shooter Xevious. While it retains the original game’s precise shooting mechanics, it introduces a highly controversial “puzzle-based progression” system that made it both fascinating and frustrating for players.

The game continues the series’ sci-fi war setting, with the player controlling the Solvalou fighter aircraft in a mission to penetrate enemy territory and uncover the mystery of Gump. Unlike traditional shooters of its era, however, the narrative is minimal and mostly conveyed through stage progression rather than cutscenes or dialogue.

The most defining feature of Super Xevious: Gump no Nazo is its hidden stage-clear conditions. Instead of simply reaching the end of each level, players must fulfill specific, often obscure requirements—such as destroying particular structures, following precise flight paths, or even intentionally avoiding firing in certain situations. If these conditions are not met, the game forces the player back to the beginning of the stage, creating an “endless loop” effect that significantly increases difficulty.

This design transforms the experience from a pure reflex-based shooter into a hybrid of action and puzzle-solving. Players must rely not only on shooting skill and dodging ability, but also on experimentation, observation, and trial-and-error to understand what the game expects them to do.

Gameplay still preserves the series’ signature dual-attack system: air-to-air shots and ground-targeting bombs. It also introduces various power-ups that enhance firepower. Compared to its predecessor, the game features more diverse environments, including cloud seas, volcanic regions, and mechanical fortresses, which were visually impressive for the FC hardware at the time.

Reception was highly divided. Hardcore shooter fans appreciated the experimental nature of adding puzzle elements to a traditional shooter, seeing it as an innovative evolution of the genre. However, many players criticized the lack of clarity in its hidden requirements, which often led to repeated stage resets and significant frustration.

Overall, Super Xevious: Gump no Nazo stands as an early experimental attempt by Namco to expand the boundaries of the shooter genre. While its puzzle-driven structure did not become mainstream, it remains an important example of 1980s arcade and console game design experimentation.
