《貓鼠大戰 2》（Mappy Land / マッピーランド）由Namco 於 1986 年 11 月 26 日在任天堂 Famicom（紅白機）上推出，是《貓鼠大戰》系列的正統續作。如果說一代是一場純粹的「密室追逐」，那麼二代則將遊戲擴展成一場壯大的「尋寶環遊世界」。關卡設計更加豐富多樣，並加入多種互動道具，使遊戲操作的策略性達到全新高度。

在設計上，保留核心玩法的精髓，同時全面升級視覺與系統。不同於一代僅限於單一宅邸，本作包含六個主題世界，如鐵路鎮、叢林世界、恐怖古堡，甚至還有聖誕村。背景不再是單調的黑牆，而是充滿細節的戶外場景。Mappy 的動作也更加生動，甚至可以抓著藤蔓擺盪。音樂則延續前作那洗腦又輕快的主題旋律，並為不同關卡加入新的配樂，讓遊戲氣氛更具特色。

故事方面，目標不再只是執行公務收回贓物，而有了更溫暖的人情味。根據版本不同，Mappy 是為了結婚或慶祝兒子的生日，需要前往世界各地收集特定物品作為禮物，例如起司、戒指、聖誕禮物或棒球。每一關的目標都是收集畫面中指定的六個物品，最後安全抵達地圖最右端的目標地點。

在操作機制上，最大的變化是弱化「門」的作用，轉而強化道具使用策略。雖然蹦床依然是垂直移動的核心手段，透過道具操控敵人。使用貓薄荷或罐頭可以吸引小貓，暫時停止追擊；貓老大 Goro 看到玩偶會停下來跳舞；放置爆竹或炸彈則能震暈追兵。還可以利用場景互動，例如在鐵路關跳進小火車撞飛貓咪，或在叢林中拉藤蔓對敵人造成影響。遊戲共有四輪故事，每一輪的目標和關卡細節略有不同，完成最後一輪後，Mappy 會舉辦婚禮，擁有一個溫馨的家庭結局。

本作廣受好評，被認為是成功將經典公式發揚光大的續作。評論家讚賞豐富的地圖和主題感，使遊戲不再單調；道具系統也降低了操作難度，即使不擅長精確跳躍的玩家，也能透過策略順利通關。歷史上，它是 80 年代動作遊戲「主題化冒險」的代表作，將簡單的追逐遊戲擴展為具故事感的冒險體驗。

遊戲中最經典的回憶，莫過於「在最後一秒放下一個貓罐頭，看著原本要抓你的貓咪全部停下來吃東西」的成就感。許多玩家也記得為了拿齊最後一個聖誕襪，在充滿陷阱的蹦床間反覆跳躍的時光，完全沉浸在遊戲精巧又趣味十足的設計中。

This game, Mappy Land / マッピーランド, was released byNamco on November 26, 1986, as the official Famicom sequel to the original Mappy. If the first game was a pure “cat-and-mouse chase” confined to a single mansion, Mappy Land expanded the concept into a grand “treasure-hunting world tour.” The stages became far more varied, and a range of new interactive tools added depth and strategy to the gameplay.

In terms of design, Mappy Land preserved the core mechanics of the original while upgrading both visuals and systems. Unlike the first game’s solitary mansion, this sequel features six themed worlds, including Railroad Town, Jungle World, Ghost Town, and even a Christmas Village. The backgrounds are no longer simple black walls but richly detailed outdoor environments, and Mappy’s animations became more expressive, even allowing him to swing from vines. The iconic, catchy music of the original was retained and supplemented with new tracks that matched the tone of each world.

The story also evolved from Mappy simply recovering stolen goods for duty to a warmer, more personal goal. Depending on the version, Mappy might be preparing for his wedding or celebrating his child’s birthday, requiring him to travel across the world collecting special items such as cheese, rings, Christmas gifts, or baseballs. Each level tasks the player with gathering six designated items before safely reaching the rightmost point of the map.

Gameplay mechanics shifted focus from doors to traps and tools. While trampolines remained the core method of vertical movement, players could now strategically place various items to manipulate enemies. Catnip or canned food distracts smaller cats, halting their pursuit temporarily. The cat boss Goro stops to dance with a doll, and firecrackers or bombs can stun pursuing cats. Environmental interactions also play a role, such as bouncing into a moving train in Railroad Town or pulling vines in the jungle to affect enemies. The game features multiple story loops, with slightly different objectives and stages in each round; completing all four loops concludes with Mappy’s wedding and a heartwarming family scene.

Mappy Land was praised for expanding the original formula while keeping it engaging. Reviewers appreciated the variety of maps and themes, which solved the potential monotony of the first game. The item-based strategies made the game accessible even to players less skilled in precise jumping. Historically, it stands as a hallmark of 1980s action games embracing “theme-driven adventure,” transforming a simple chase game into a story-rich experience.

The most memorable moments often come from using a single item at just the right second—dropping a can of food and watching the pursuing cats stop to eat, granting a fleeting sense of triumph. Many players also recall bouncing endlessly between trampolines to collect the last Christmas stocking, fully immersed in the game’s clever and playful design.
