Developed and published by Capcom in 2000, Resident Evil Code: Veronica served as the fourth installment to this successful series. The franchise, known as Biohazard in Japan, coined the term survival horror, a genre characterized by limited ammunition and health, dark and complex environments, and a feeling of isolation due to a low number of non-player characters. Initially released for Sega Dreamcast, and the first Resident Evil game released for a non-Sony console, gamers and critics alike praised the game's ability to create a truly terrifying atmosphere. The single-player game, viewed mostly in third-person perspective, centers on three characters: Claire and Chris Redfield, and Steve Burnside. The player alternates between controlling Claire, Chris, or Steve based the game's storyline. Claire, while searching for her brother Chris, of the S.T.A.R.S. unit, is captured and imprisoned on the mysterious and dangerous Rockfort Island. Claire joins forces with Steve, another prisoner, and they both attempt to fight their way off of the island. Meanwhile, Chris is also searching for Claire and eventually joins the battle. Code: Veronica is named so because of the T-Veronica virus, a secret and illegal scientific experiment that mutates life forms on the island. The player must solve puzzles and find items in order to enter different areas of the island, the ultimate goals being to save their allies, discover the island's mysterious secrets, and, most importantly, survive. Code: Veronica's gameplay mimics that of Resident Evil 3, as the games were developed in conjunction with one another. The player can continue to use randomly placed explosive objects, and new weapons such as the crossbow have been added. The first game in the series to use 3D backgrounds, Code: Veronica also utilizes first-person perspective for a limited number of weapons. After completing the main game, the player can unlock a minigame titled Battle Game, as well as extra weaponry. In 2001, Capcom remade Code: Veronica for the PlayStation 2, alternatively called Code: Veronica X. It features updated graphics and additional cutscenes. In 2003, Capcom ported this remake to the Nintendo GameCube console. Counting Code: Veronica as both a commercial and critical success, the franchise continued to spawn several more sequels, novels, and even a film series.
