Rocket Knight Adventures is a side-scrolling platform game where the player guides Sparkster through linear levels.
The player can jump and attack using Sparkster's sword, which can either hit enemies directly or by emitting energy projectiles that travel a short distance.
The game features four difficulty options, with harder difficulties increasing the power of the enemy attacks and reducing the number of lives and continues the player starts with; the hardest starting with no lives and continues, and enemy attacks defeating Sparkster in one hit.
Around this time, an orphan named Sparkster was taken in by Mifune Sanjulo; a friend of the King, and current leader of the Rocket Knights.
Sparkster heads to the Zephyrus castle to find Axel Gear kidnapping Princess Sherry, who is the one who knows the location to the key.
Sparkster frees Sherry, while Devilgus escapes into space with the seal key to reach the Pig Star.
Sherry casts a spell on Sparkster's rocket pack that allows him to fly in space and reach the Pig Star.
After a melee fight with Axel Gear which results in his defeat, Sparkster eventually confronts the Pig Star's core, whom was the commanding force of the Devilgus.
