Steins;Gate Drama CD Alpha, Beta, and Gamma

Steins;Gate Drama CD Alpha, Beta, and Gamma, stylized as α, β, and γ, are a trilogy of audio dramas based on the 2009 video game Steins;Gate, and are part of the Science Adventure series. It follows Kurisu Makise, Mayuri Shiina, and Rintaro Okabe, three characters from the Steins;Gate game, in three different alternative histories. Alpha shows Kurisu's actions during the tenth chapter of the video game, Beta shows what happened after Okabe failed to save Kurisu, and Gamma shows a reality where the Year 2000 problem caused a disaster and Okabe became an agent working for the organization SERN.

The audio dramas were originally published as three CD albums by 5pb. between March and June 2010, and were later collected along with other Steins;Gate material in a 2016 box set. They feature voice acting by the cast from the Steins;Gate game, and music and cover art by the game's composer Takeshi Abo and character designer Huke, respectively. The dramas were well received by critics and popular with fans, leading to the creation of manga and light novel adaptations. They were also used as the base for the Epigraph Trilogy of light novels and the Steins;Gate 0 video game. The trilogy was recorded in Japanese, but all three drama has gotten an English fan translation.
