Fossil Fighters: Champions follows the first game very closely, adding a few small items but keeping the framework of the previous game. Gameplay consists of collecting fossils to revive them into monsters known as "vivosaurs", and using them to battle other vivosaurs. Players will gain fossils by purchasing them in shops, obtaining as rewards for quests, or digging them up in specified locations indicated by a sonar. Two new fossil rocks are added; the Wonderous Fossil rock that changes color and improves a Vivosaurs stats and the Miraculous Fossil rock that evolves it into a new form.
Cleaning[edit]
Fossils must be cleaned before they are able to be revived. The player uses either a hammer or a chisel, each with different strengths and weaknesses, in a cleaning minigame using the DS touchscreen to remove the surrounding rock. The minigame has a ninety-second time limit as well as a meter to show how much of the fossil is revealed and how severely damaged it is. Two new types of fossil rock are added from the previous game. Giant fossil rocks contain all four fossils for a particular vivosaur in one complete skeleton. The other are odd fossil rocks which have two sides, allowing the player to flip between them while cleaning.[1]
Revival[edit]
Getting the head fossil is mandatory to revive a creature, while the other three parts serve to make it considerably stronger. Many vivosaurs return from the original game. Newly added vivosaurs include mollusks, mammoths, and sabre tooth tigers.
Battle[edit]
Fossil Fighters: Champions uses the same battle system as its predecessor. Along with an associated element, Vivosaurs are categorized by what range they best attack at: short, medium, and long range. Both sides are able to rotate their three players on the playfield to move their vivosaurs into their strongest range to maximize damage. The team who has the higher total speed goes first in a battle, as opposed to the previous game, in which the team with the lower total LP goes first.
Added features[edit]
The player can now play as a girl instead of the default boy and choose from four different starting vivosaurs. The game also adds the toggle for Auto Battle as well as the ability to rotate own team. Players can now unearth rare gold fossils that can be used to "super evolve" certain vivosaurs into new forms.
