Popular games for collection D series

A survival horror video game developed by WARP for the Dreamcast. It was published by WARP in Japan in 1999 and then by Sega in North America in 2000. D2 was written and directed by Kenji Eno, and serves as the third and final entry in the D series after D and Enemy Zero. Like the previous two games, D2 stars the digital actress Laura and serves as an independent story unrelated to either game. D2 is also WARP's final game before changing their name to "Superwarp" and transitioning from video game development to online network services in August, 2001.

The first entry in the D series and one of the first games released by the company, it dealt with taboo content such as violence and cannibalism, featured 3D CGI full-motion video and a first-person perspective, It was the first game to star the digital actress, Laura.

Enemy Zero was the second game to star the digital character Laura Lewis—the first being D. In E0, gameplay sequences alternate between interactive FMV and real time exploration, both from a first person perspective. The interactive FMV component uses gameplay identical to an earlier Warp game, D. The real time component of E0 is unique. Enemies are invisible, and location is only possible through the use of sound, with notes of different pitch helping the player find the distance and direction of enemies. Additionally, every gun in the game must be charged up immediately before each shot, and charging a shot for too long will cause the charge to dissipate, after which the charging must start over. Since all available guns have very limited range, this makes timing crucial; beginning to charge the gun too late or too soon will allow the enemy to reach Laura, resulting in an immediate game over. In Enemy Zero, reloading the gun and moving the character around are mechanics that have been made intentionally slow,[4] which stimulates players to avoid combat and direct contact with the alien enemies as much as possible. In the early segments of the game, avoiding detection is not only recommended; it is required, since the player has no means to defend him or herself without a gun. Enemy Zero is an example of a game containing stealth elements[5] roughly two years before the release of Metal Gear Solid popularized the genre worldwide, though ten years after Metal Gear started the genre in 1987.
