Chapter 1: Sea of Flames (Dirge of Cerberus)
A trio of soldiers approach on the rooftop behind Vincent. From their line of vision we see a sort of computer screen with the words "Vincent Valentine", "Gender: "Male", "Blood Type: "A" at the top left of the screen. We cut to a scene of a girl with an elaborate device covering the top half of her head.
The camera pans out as we see she's plugged into a collection of wires. Back to the soldiers, whose screen notifies that Vincent is wanted Dead or Alive. They spring to action, but Vincent is faster and shoots them all down.
The gameplay begins; Vincent traverses several rooftops, killing many of these soldiers, eventually reaching the ground.
Vincent continues through the streets, saving civilians when he can, with dialogue that's unimportant to this script. We see a scene of a helicopter carrying away a container filled with people. Vincent goes about his business. We see a scene of a mother and daughter running away from a horde of dog-creatures; we see a similar screen as the guards who saw Vincent Valentine saw. The girl has a green tint with the word "Clean" beside her. The mother has a red tint with the words "Geostigma detected" beside her. One dog creature pins down the mother while another dog drags the girl away, and takes her inside a container. Vincent finds the container and frees her; the girl runs away crying "Mommy!", to which the mother replies "Rio!"
Vincent continues through the town, saving civilians and generally killing a lot of bad guys. Eventually he gets to the town square.... and a helicopter faces him. Boss battle vs. Dragonfly. At the end of the battle the Dragonfly fires off a few missiles before crashing - Vincent dives into a nearby house via its open doorway to avoid them.
Cut back to the girl with the strange headgear. She takes off the helmet.
A closeup of her face reveals her eyes are bright orange.
Her eyes return to a blue colour. A rather large brute approaches her from behind.
Back to Vincent, who makes his way through the house. On the 2nd floor, a loud crashing is heard; there's a big hole in the wall, and in walks the large brute from before. He's muscular, has blue hair and almost appears more beastly than human. The girl accompanies him.
Her eyes turn orange.
Vincent just looks at them.
Several soldiers in the room also shout "Heil Weiss!"
Gameplay: "Vincent kills them all. Back to the large brute.
The girl suddenly faints. He looks at her. A random voice off-screen says "This way!"
He picks up the girl and walks away.
The brute turns around.
The voice from before enters the room.
In runs Reeve and a guy in a white uniform.
Reeve turns around, and we see several enemy soldiers entering the ground floor of the house.
Reeve begins to walk away.
Reeve stops and partially turns around.
A hail of gunfire bursts through Reeve's stomach; Vincent shoots down the enemy soldier, before running to Reeve's side.
He goes to pick up "Reeve", who falls apart into several pieces. Out pops Cait Sith.
Vincent departs the house and continues to go around Kalm, assisting the WRO and killing enemy units. To give you some insight as to who the WRO is, I'll include some optional dialogue Vincent can have with one WRO member.
Eventually he reaches an open area in front of a church. The Dragonfly from before shows up! Boss fight vs. Dragonfly GL. After the boss fight, Vincent jumps into the air, fires at the Dragonfly a few times, then, landing on top of it, transforms into the Galian Beast and punches it. He jumps off, the helicopter explodes, and he transforms back to Vincent. Enemy soldiers emerge from the vicinity and fire at Vincent; a truck drives in front of him, shielding him from the gunfire; WRO members pour out the back and return fire, accompanied by the real Reeve, who nods at Vincent. Vincent nods back.
Scene change; relative calm has been restored to Kalm (no pun intended). Vincent sits on a crate while Reeve is talking to a WRO commander. At the end of the conversation they salute, followed by Reeve walking over to Vincent.
Vincent looks down... he's got a job to do.
Scene change: "two WRO members are taking cover behind crates. One of them is engulfed by black smoke.
He turns around to see no one is there, before being engulfed himself. We see a group of four WRO Members running by, with the fourth one being engulfed by the smoke. The remaining three run into a warehouse.
A noise is heard above and the WRO Members look up. A scantily-clad girl with red hair and red eyes holding a weapon of some sort smirks at them. Her voice sports a slavic accent.
Her weapon opens up. Instantly she appears behind the three WRO members and in one broad move slashes them in their necks. They fall down.
