Zoids Saga DS: Legend of Arcadia is the conclusion of the Zoids Saga series. It comprises scenes from Zoids Saga, Zoids Saga II (released in the west as Zoids: Legacy) and Zoids Saga III: Fuzors. It features upgraded graphics and sound. Additionally, Zoids and story elements from the Zoids Genesis anime have been included.
The game plays like a traditional JRPG with the player controlling characters and mechs from the Zoids titles. Enemy Zoids wander around the overworld and chase you on sight, which takes the player into the turn-based combat system. An English patch for the game done by Traceeytrace in 2022.
The gameplay is the same as Zoids Saga except that Takara Tomy used the DS split screen feature to introduce the radar system. Regina gave him a peculiar device which he wore on his left arm called Arm Retcomm, a radar watch device with map, item locator, trap, and Zoids mining system. Right now, you only have level 1 of these systems, but you will get more upgrade for the device starting from midgame.
The party heads to Red Rock Cave located Southwest from the city. Here, RD said to Helmut that there's something suspicious about the place and Helmut warned the party to be on guard as enemies will pounce on us. RD tell the party to keep moving. At B1 Floor, RD speculated that the place is some sort of hideout by looking at the enemy's movement which Sigma said to not let the culprit get away and Helmut suggests the team to split up and go ahead. Jack told Helmut to let them know if something happened and RD's team left the party. At the end of B2 Floor, the party encounters Gale, the culprit behind the missing Zoids. Gale managed to exploit the situation when they let their guard down and escape. It was at this time, Jack tell everyone about his past.
In the middle of conversation, Gummie's team found them and thought that they're the culprit behind the missing Zoids. Regina told them that they caught the wrong person but the Peacekeeping Bureau won't listen and Jack asked the prince what to do. Athle tell his bodyguards that talking won't do anything and they have to fight their way through as they can't get themselves arrested by the Bureau. After the battle, RD found the party and Bureau fighting each other. "Gummie, Athle! What are you doing!?" RD yelled. Gummie sees RD and stop. RD tells Gummie that the culprit escaped in the Gojulas they just encountered earlier and Gummie realized that they caught the wrong person. As an apology for the misunderstanding, he tells the party that they decided to join and help catch the culprit.
Back in Blue City, Amy suddenly enters to tell everyone that Matt's Leo Blaze has been taken by the man in Gojulas. Since RD already went ahead, the party sees him battling a Fuzor Dragon and Gojulas. The man piloting Matrix Dragon, Watts took Matt's Leo Blaze and fused with it. Poor Matt can only watch Watts render Liger Zero Phoenix's into freeze mode. The party carry RD and his Zoid back to Blue City
