Resident Evil Code: Veronica is the fourth game in Capcom's Resident Evil survival horror series originally released for the Sega Dreamcast in 2000. It's notable for being the first Resident Evil title to debut on a non-Sony platform, as opposed to the first three installments, which were originally PlayStation games before being ported to other platforms. An updated version of the game titled Code: Veronica X was released for the Sega Dreamcast (Japan only) and Sony PlayStation 2 in 2001. This new version includes new cut scenes spliced into the main game and mild graphical changes. It was the first game in the series made for a sixth generation console, and also the first core title in the series, prior to the release of Resident Evil 4, to use full polygonal environments over the static, pre-rendered backgrounds that characterized the series. Code: Veronica is the first Resident Evil game in the main series to use 3D backgrounds instead of the traditional pre-rendered ones. Despite this, the camera does not follow the player around, but swings between semi-fixed angles (similar to the original Dino Crisis). However, two weapons in the game (a sniper rifle and a linear launcher) can be fired from the character's point of view and a first person view mode is available in the game's unlockable "Battle Mode" minigame.

Easy Hawk Emblem.
After you've collected the TG-01 go back to the 3-D duplicator and before putting in the Hawk Emblem and TG-01 into the machine, walk through the metal detector with any metallic object to sound the alarm.(while on the 3-D duplicator side or you will be locked out.) With the shutters down the three zombies cannot break the windows. After the 3-D duplicator is finished all you have to do is push the button to lift the shutters and take the duplicated Hawk Emblem without losing any health.
