Resident Evil: Dead Aim (Japanese Gun Survivor 4: Biohazard - Heroes Never Die) is the fourth release in the Gun Survivor series and the first to feature third-person movement, similar to its predecessor titles in the Resident Evil series. Capcom were able to develop and release this game on the Sony PlayStation 2, as Capcom's exclusivity contract with the Nintendo GameCube console pertained only to games regarding the main story in the series, whereas Resident Evil: Dead Aim is an expanded universe title, having virtually no plot involvement with its earlier releases. A mid-western town in the United States called Raccoon City was destroyed when a mutagenic viral weapon known as the T-Virus was leaked into the Arklay Mountains in May of 1998, followed by the release of the T-Virus and G-Virus into the sewers of Raccoon City in September of the same year. The resulting incident forced the United States government to destroy Raccoon City via surgical missile strike after most of the population was infected with the leaked viral strains, becoming homicidal monsters. Although the Umbrella Corporation was implicated in the incident and severely pressured by outside influences to confess their crimes and abort their research, they refused to do so, conducting further research into the strains in clandestine, secluded laboratories. When a large amount of a recently developed hybrid viral agent, known as the T/G-Virus, is stolen from Umbrella's Paris lab facility by a former Umbrella researcher then released onboard an Umbrella-owned luxury cruise ship, Bruce McGivern is sent in by the U.S. government to retrieve the virus and neutralize the threat.

Secrets

Play as Fongling for the majority of the main game
To play as Fongling for a majority of the game (rather than control her for a little bit),
beat the game once on any difficulty mode (So Sweet, Recommend, Extreme) and then when replaying a new game from the same save file, select YES when prompted, and then you'll start as Fongling. The game remains exactly the same as if you were playing the game as Bruce.

Here's the last boss fight, a pretty neat video:
