《雙截龍》（ダブルドラゴン / Double Dragon）是由早期的日本軟體公司TECHNŌS JAPAN於1987年推出的街機遊戲，並於隔年移植到紅白機，以美國幫派格鬥為背景。

人物設定以武打巨星李小龍為基礎，故事主角是經營武道館的雙胞兄弟比利(Billy Lee)和吉米(Jimmy Lee)。無論是空中迴旋踢還是過肩摔等武打動作，都展現濃厚的截拳道風格。《雙截龍》在FC平台上推出三款作品，同時也在NEO GEO、SEGA、Game Boy和GBA等其他主機上推出其相關作品。

GB版本讓玩家可以透過連線主機與朋友進行對戰。遊戲主要以單人模式進行冒險，若無法擊敗畫面中的敵人，將無法繼續前進。雖然敵人只有六種類型，但卻會使用多種招數進行攻擊，而GB版則有八種絕技。

畫面左下方分別顯示體力表、額分和剩餘生命。在兩人對戰時，只會顯示體力表。

故事情節中，玩家需要救出被敵人擄走的女友。GB版的敵人與FC及大型電玩版本相似，共有四個大關，其中有些許修改，但差異不大。第一關是貧民區，第二關是工廠，第三關是森林，第四關是敵人的最終要塞。

在大型街機中，兩位男主角在打敗最終頭目後進行最後對決，贏得的人最後抱得美人歸。在GB版中的最終關卡，可以移動到地板的最下方，然後將難纏的敵人用上勾拳擊出，這時候他們就會掉落在下方的釘牙上瞬間死亡，即使是拿著機關槍的最終頭目也是一樣有效，運用此技巧就能輕鬆迎來結局。

整體遊戲攻略相對簡單，只需記住招式，消滅畫面上的敵人，並熟練必殺技，如過肩摔和飛踢等，將對遊戲進行大幫助。在GB版中，可以使用球棒和汽油桶等武器，但一旦移動到另一畫面，這些武器就會自動消失。

"Double Dragon" (ダブルドラゴン/雙截龍) is an arcade game released by the Japanese software company TECHNŌS JAPAN in 1987. It was later ported to the Famicom/Nintendo Entertainment System (NES) the following year, featuring a storyline set in the context of American gang fights.

The character design is based on the martial arts legend Bruce Lee, featuring the main protagonists, the twin brothers Billy Lee and Jimmy Lee, who run a martial arts gym. Whether executing aerial spin kicks or shoulder throws, the game showcases a strong influence of Jeet Kune Do. "Double Dragon" saw the release of three versions on the NES platform and spawned sequels on other consoles such as NEO GEO, SEGA, Game Boy, and GBA.

The Game Boy version allows players to engage in battles against friends through a linked console. The game primarily operates in a single-player mode, and failing to defeat enemies on the screen impedes progress. Although there are only six types of enemies, they employ various martial arts moves, with the GB version featuring eight special techniques.

The lower-left corner of the screen displays the health bar, score, and remaining lives. During two-player battles, only the health bars are visible.

In the storyline, players embark on a mission to rescue a kidnapped girlfriend. The enemies in the GB version are similar to the FC and arcade versions, consisting of four main stages: the slums, the factory, the forest, and the enemy's final fortress.

In the arcade version, after defeating the final boss, the two male protagonists engage in a final showdown, with the winner earning the privilege of rescuing the damsel in distress. In the GB version's final level, players can move to the bottom of the floor and use uppercuts to knock difficult enemies onto spikes, instantly defeating them. This technique is effective even against the final boss wielding a

machine gun, making it an easy path to the conclusion.

The overall gameplay strategy is relatively simple, requiring players to memorize moves, eliminate enemies on the screen, and master special moves such as shoulder throws and flying kicks. In the GB version, players can use weapons like a baseball bat and an oil drum, although these weapons automatically disappear upon transitioning to another screen.
