Sparkster: Rocket Knight Adventures 2 (スパークスター ロケットナイトアドベンチャーズ2, Supākusutā Roketto Naito Adobenchāzu 2) is the sequel to the Sega Mega Drive/Genesis game Rocket Knight Adventures. Another game under the same title, Sparkster, but without the Rocket Knight Adventures subtitle and not continuing the plot of the first game, was released on the SNES. A follow up game is Rocket Knight.

The North American version of this game is simply known as Sparkster.

Sparkster's gameplay is very similar to its precursor. The game largely functions as a 2D sidescrolling platformer, with an autoscrolling airship stage being the lone exception. The player is able to jump, attack with Sparkster's sword, or use his rocket pack to fly.

The primary gameplay difference is how the use of the rocket pack changed. In Rocket Knight Adventures, it had to be charged manually, and took a relatively long time to do so; its use was primarily strategic and planned, and sustained flight was generally not possible. In Sparkster, the pack charges quickly and automatically, allowing the player to use it more conventionally and remain airborne indefinitely.

A duel with Sparkster's arch rival Axel Gear occurs, much like in the first game.

Gold Sparkster

The main difference between this game and the rest of the series is the inclusion of six secret swords hidden within the levels (as well as another earned by clearing the prologue level). A player who can obtain all seven will face the final boss as Gold Sparkster, similar to Super Sonic from the Sonic the Hedgehog. Gold Sparkster hits harder than normal Sparkster and his rocket pack charges faster. However, he is still able to sustain damage.

Completing the game as Gold Sparkster is necessary if players want to see the 'True' ending. If the game is completed without transforming into Gold Sparkster, a message will appear saying 'Try Again.'
