  • It’s gonna be a WILD ride

I. Setup & Premise

  • The Lost Episode and COVID
  • The pitch: A caveman in a baseball cap and grass skirt throws axes. He eats fruit or he dies. His girlfriend got kidnapped again. There are eight islands to explore
  • North America actually got it before Japan, which received the Famicom version in April.
  • The first Adventure Island was essentially a licensed port — Hudson acquired the gameplay engine of Sega's Wonder Boy arcade game from developer Escape, swapped out the characters and music since Sega owned those, and shipped it as their own NES title.
  • Adventure Island II is the first entry in the series developed entirely by Hudson independently.
  • The central tension worth dwelling on: the first Adventure Island was a tight, brutal, single-minded experience — run right, don't stop, eat fruit, throw axes, survive. Five years passed between it and this sequel. What Hudson came back with was a game with more exploration and branching paths.

II. What Makes It Stand Out

  • The world map and branching paths holds up
  • The first Adventure Island had no map. Eight worlds, each a string of linear stages leading to the next. Adventure Island II introduces a top-down overworld for each island, showing the available stages as nodes connected by paths.
  • Depending on how you play you may reach the island boss by clearing only a fraction of the available stages ala Super Mario Bros 3.
  • This is a real structural improvement. It gives skilled players a faster path and rewards exploration without punishing players who take the long route. It also means repeat playthroughs feel genuinely different, because the islands aren't fully mapped in your head after a single run.
  • When you fail to beat an island boss, they relocate to a different stage on the map. You have to hunt them down. It's a small touch that keeps the world feeling alive rather than static
  • The inventory system holds up
  • Between stages, Adventure Island II lets you carry items forward. Weapons collected but not consumed, dinosaurs rescued but not yet ridden — they go into an inventory screen that you can draw from at the start of the next level.
  • This means preparation is possible. Going into a boss stage, you can choose which companion to bring. Heading into a water level, you pull out the aquatic dinosaur you've been banking
  • Finding a hidden Hudson bee logo in a cave on the first island prevents your entire inventory from being wiped when you game over.
  • The four dinosaurs holds up
  • This is the game's headline feature and it earns the attention. Each of the four companions has a distinct ability that changes how you interact with specific level types:
  • The red Triceratops breathes fire — useful for offense and, crucially, lets you enter lava-filled levels without instant death.
  • The blue Triceratops is steady and non-slip on ice, making it the essential companion for the frozen island.
  • The Pteranodon (tuh-ran-uh-don) flies — hold the button, float above the level, bypass ground-based obstacles entirely.
  • The water dragon excels in underwater stages, turning the slow, awkward underwater movement of the base game into something fluid and manageable
  • Each dinosaur also functions as a free hit point. Take damage while mounted and you lose the companion rather than your life.
  • The hunger bar mixed
  • Inherited from the original. Your energy meter depletes constantly while moving, and collecting fruit is the only way to refill it. Let it hit zero and you die regardless of how many hits you have left
  • Always moving, always looking for the next piece of fruit — is the series' most distinctive mechanical fingerprint
  • Whether it holds up is a legitimate debate. The argument for it: it keeps the pace aggressive. Adventure Island is not a game that rewards cautious play or standing still. The hunger bar enforces forward momentum and turns idle exploration into a calculated risk. The argument against it: by 1991, the NES library had conditioned players to expect that health bars depleted by enemy contact, not the passage of time. The hunger mechanic is strange, slightly punishing, and not explained in a way that new players immediately internalize. Die from starvation while your health bar reads full and you've learned something the hard way
  • The secret warp rooms and hidden eggs holds up
  • Scattered throughout the levels are invisible breakpoints — areas where throwing an axe at empty air will crack open a hidden egg containing a warp, a free dinosaur, or a power-up. Nothing on screen telegraphs these locations. You find them by attacking constantly as you run, or by following a tip from a friend, a magazine, or thirty years of accumulated wiki knowledge.
  • The debug menu buried in the game's code — one of the most comprehensive ever found in a retail NES release — lets developers see where every hidden egg is. That menu was never meant to be found, but it exists, fully functional, accessible with a specific button sequence on the title screen
  • WORLD SELECT: To access this level select menu, on the title screen, press Right, Left, Right, Left, A, B, A, B.
  • DEBUG: use the Game Genie code AASXEXZA and then use the world select screen.

  • The bosses mixed
  • A significant improvement over the first game's largely interchangeable boss encounters. Each island's boss is visually and behaviorally distinct, requiring a different approach rather than the same pattern applied repeatedly.

III. Pop Culture, Legacy & Connections

  • The Wonder Boy divergence: By 1991, the Wonder Boy series that birthed the original Adventure Island had already moved on. Wonder Boy III: Monster Lair, Wonder Boy in Monster Land, and Wonder Boy III: The Dragon's Trap had all shipped — evolving the franchise toward action RPG territory, open exploration, and character progression.
  • The Super Mario Bros. 3 shadow: Adventure Island II arrived in North America in February 1991 — about a year and a half after Super Mario Bros. 3, which had launched in the US in February 1990. The world map structure, the branching paths, the item inventory, the varied world themes, the dinosaur companions that absorb one hit — the DNA is obvious.

IV. Closing Bits

  • Adventure Island II is the rare sequel that improves on its source in almost every measurable way — more variety, better structure, more interesting companions, a deeper inventory system. And yet it sits in the shadow of the Mario games it was clearly studying, judged not against what it came from but against the best the platform ever produced.Can a game be genuinely excellent and still be overlooked because it was competing with the greatest platformers ever made on the same hardware?
