Gameplay
The gameplay for Cross Serpent 2: Victory Burst is overall the same as its prequel. This game introduces the Duo Blitz, a technique where the player character summons their Crossgene beast to perform a team attack against the enemy. This time around, players have a choice to choose one of two groups: the Virus Blitz (Kato, Dai, Kidd, and Fon) and the Spirit Barriers (Oscar, Dabu, Miriam, and Jose).

Plot
Two years after the events of the first game, the Virus Blitz has reunited after an encounter with a group called the Spirit Barriers. The Spirit Barriers have a similar goal, but instead they want to cleanse the world of Crossgenes so that no one will have to suffer from the cruel virus like five years ago. However, the two groups do have a common enemy, the Retix Corporation. Their goal is to accelerate the evolution of Crossgenes into a source capable of bonding with other life forms, so that they can form their own military force of Crossgene hybrids. Jessica Ambers, who once worked for the Retix Corporation, joins the Virus Blitz to help them infiltrate their fortress.
