As in the original Dragon Spirit, players must take control of a prince transformed into a dragon by a flash of lightning: the first controls "Huey" (blue) and the second player controls "Siria" (red), which means that two players can now play simultaneously; Huey also looks like an 8192-colour version of Prince Amul from the original game, and both players can now press and hold their Firing Buttons to make their dragons spit flames continuously (and, if they wait for a few seconds without pressing them, charge their shots).
Several new enemies and powerups have also been introduced - and, much like in Phelios, Huey and Siria can take up to four hits before dying (depending on what the arcade operators set the "LIFE" option to), which means that if they have set it to "1" they will die immediately when they get hit.
Dragon Saber was the creation of Namco artist Yoshihiro Sugiyama, being his first time as a planner for a game.
[1] Sugiyama wanted the game to feel like a true continuation of its predecessor Dragon Spirit in terms of its storyline and world, as he felt the NES sequel Dragon Spirit: The New Legend was mostly just a rehash of the original and had a rather generic premise.
[1] He also wanted the game to appeal to anyone instead of mostly hardcore shooter enthusiasts, and one that many could find a degree of satisfaction in.
