ABOUT THIS GAME

A classic worth
one more run.

Adventure Island II replaces the linear island chain with a world map of branching levels, and adds the ability to switch between dinosaur companions with distinct skills. Hidden areas, bonus stages, and a more forgiving checkpoint system make this the most approachable entry in the NES trilogy.

“The best retro games don’t ask for nostalgia. They earn it all over again.”
PLAYER'S GUIDE

What to know before you play

How Adventure Island II plays

Adventure Island II trades the single linear path for a world map with branching stages and secrets. Dinosaurs are now carried between levels as eggs and hatch into companions with unique traits, from flying to fire-breathing. Hidden exits and bonus stages add a light exploration layer to the platforming.

Why it still matters

The sequel is often remembered as the friendliest entry in the series: checkpoint improvements, a map, and dinosaur eggs made it more welcoming than its predecessor while keeping the core stamina challenge. It cemented the series’ signature mix of sunny presentation and demanding timing.
