(Capcom's primary storyline)
Steve Burnside (スティーブ・バーンサイド Sutību Bānsaido ) was a prisoner sent to Rockfort Island along with his father. This was due to his father, an Umbrella employee that was selling the company's secrets at auction, but he was caught. He and Steve are taken prisoner while Steve's mother was killed.
"You'll just end up disappointed if you rely on others. Believe me, I know!"
— Steve to Claire.
Steve and his father are imprisoned in Rockfort Island's prison until it was taken over by the H.C.F.. During the course of his escape, Steve and his father became separated. However, Steve managed to survive the zombie onslaught caused by the sudden outbreak of the experimental t-Virus.
Some time later, Steve met Claire after attacking her on the presumption that she was a zombie. However, Claire shot the light that he shined on her and defended herself. These actions caused Steve to realise his error and cordially met her face to face. Steve left Claire in order to procure an airplane to escape the island.
When Steve was found again in the monitoring room which was the room after the 3D Auto-Duplicator device, he was looking the information up on Chris Redfield. When Claire asked him what he was doing there, Steve asked Claire if Chris was her relative. Claire asked him if he meant her brother and Steve realised the fact that they are siblings. He tapped on the lever that released the lock on the door, saying "Well, it seemed that your brother was under surveillance by Umbrella." After Claire e-mailed Leon to tell Chris that he was being monitored as well as the coordinates of the island, Steve said that Chris would not come and Claire would "just end up disappointed if she relied on others." Steve stormed out of the room.
Steve took the Gold Lugers in the island's Palace. Because of his attitude, he did not realize that he could put them back and disable the trap that he set off. When Claire released the trap, Steve claimed the Lugers, saying that he found them (Although Claire was the one who found them first) and he was keeping them. Then, he proposed a deal to Claire, a fully-automatic gun for the Lugers. When Claire was thinking, Steve said that he would see her around and bolted out of the room, leaving Claire alone once more.
When Claire was almost killed by a Bandersnatch, Steve jumped through a window and shot the creature. While he was still looking at Claire, he shot the Bandersnatch at least five times before looking at it. After Steve kicked the B.O.W., he shot it one last time before the Lugers ran out of ammunition. Because Claire had the Sub Machine Guns with her, she gave them to Steve in return for his Lugers. He found out that they are empty and accused Claire of cheating. When Steve learned that there was a full magazine for the machine guns, Steve gave Claire a boost so she could retrieve it. After Steve took the full magazine, Alfred Ashford took both Claire and Steve down to the B1 floor, thinking that they would die there. However, Steve cleared all of the zombies from their path so Claire was able to go through easily. Steve said to Claire when she arrived that the machine guns are "a lot more reliable than any person." After Claire asked Steve where his family was, he was enraged. When they reached the second floor, Steve and Claire both fell off an unstable part of a walkway.
In the aftermath of the fall, Claire's foot became trapped under the rubble. As Steve got onto his feet, he encountered his father, now infected with the t-Virus. Unable to shoot him, Steve was unable to act. Just when it seemed that he would reach Steve, Claire unintentionally attracted his father's attention. Steve shot his infected father down just as he was about to bite Claire. However, in shooting his father, Steve completely depleted the ammunition loaded into his Sub Machine Guns.
After coming to grips with what he did, Steve told Claire about how he and his father came to be on the island. Afterward, Claire left Steve alone to continue with coming to grips with his loss.
When Claire was about to be killed by Alexia, Steve stormed in. He was wounded by a gunshot, but he opened fire and wounded Alexia. As he and Claire checked the room, they are attacked by Alfred. Steve kicked Alfred to the floor and they discovered that Alfred, having a split personality was playing Alexia. They escaped the residence after the self-destruct system was activated.
They both evacuated the island via a plane that closely resembled a C-130 Transport. Steve piloted the plane off the island, but Alfred set the plane to auto-pilot and it flew to the Antarctic Facility.
"I'm glad that I met you... I... I love you... Claire..."
— Steve's last words.
Upon reaching Antarctica, their plane crash-landed into the Antarctic Base which was infested by the infected on the other planes.
After a search of the facility, the two encountered an armed Alfred. Claire was held at gunpoint, but Steve was able to get the drop on Alfred, shooting him with his submachine guns. The impact of the rounds caused Alfred to stagger backward against a railing which broke away and caused him to plummet down a hole.
They explored the outside of the facility where an escaped Alexander found them. Steve was pushed off the roof and nearly fell to his death. Claire managed to lift him to safety after killing Alexander. When Claire started walking, he said, "I swear I'll protect you next time, Claire."
The two are captured by Alexia and Steve was injected with the t-Veronica virus. He mutated in front of Claire and attempted to kill her with a giant axe. When she locked herself up in a cell, one of Alexia's tentacles broke through the wall and grabbed a hold of her.
When Steve broke into the room, he aimed his axe high, ready to kill her. But, his body managed to fight against the virus and his newly regained consciousness allowed him to strike the Alexia-Pod. The remainder of the Alexia-Pod caused him to hit very hard to a wall.
While dying, Steve quickly reverted to normal and told Claire that Chris kept his promise and he loved her, but was unable to fight anymore. He succumbed to his injuries. He was only 17 at the time of his death.
The H.C.F. managed to collect his body to take the samples of the t-Veronica Virus. Albert Wesker told Chris that it might be possible to revive Steve and maybe even see Claire again. Of course, this was clearly a jab at Claire's emotions which angered Chris and Claire.
When contacted by Javier Hidalgo, Albert Wesker took a sample of t-Veronica from Steve's corpse in order to provide the virus for Hidalgo's ailing daughter, Manuela Hidalgo. In exchange, Wesker was given a large sum of money and a stake in Hidalgo's crime operation.
