Robot Alchemic Drive

The protagonists that the player may choose between are two males and one female (Naoto Tsukioka, Ryo Tsukioka, or Yui Tsukioka), but the character is only referred to as "Chairman" and the choice bears no impact on gameplay. There are three different robots to choose from: Vertical Fortress Vavel, Airborne Dominator Laguiole, and Gllang the Castlekeep.

Vavel has two modes, Volcanic and Genesis mode.

As the seventeen-year-old sole inheritor to the Tsukioka family and their bankrupt weapons company, the game introduces the player to a world where all crewed space exploration projects have been put on hold indefinitely due to a material called "Space Nectar" that poisons and kills any organic life in space. Earth is safe because of its atmosphere, but it seems that humanity is doomed to an isolated existence. When machines known as Volgara begin destroying the Earth, the player must pilot the only weapon on Earth capable of standing against the invaders. Along the way, lives will be changed, history will be made, and the origins of the Volgara will be revealed.

Robot Alchemic Drive was developed by Sandlot, a company created by former employees of Human Entertainment. The game's engine was originally intended to be for a game based on the tokusatsu series Tekkōki Mikazuki and even received a playable demo, though the full game was later cancelled, likely due to the commercial failure of the show itself. Robot Alchemic Drive's gameplay and controls are heavily inspired by Remote Control Dandy (1999), a game that was previously developed by Sandlot and published by Human Entertainment for the PlayStation.

The characters of the game were designed by Toshihiro Kawamoto, the character designer of the Cowboy Bebop anime series. Development of Robot Alchemic Drive took approximately 16 to 18 months to complete. Much of the game's use of incredibly large robots was inspired by anime. The game was aimed at both casual and hardcore gamers, as well as fans of action games and robot games. The hardest part of development was to handle the sense of scale involved with the robots.

The game received "generally favorable reviews" according to the review aggregation website Metacritic. In Japan, Famitsu gave it a score of two eights and two sevens for a total of 30 out of 40. GamePro called it "a weird high-concept wonder that actually works, and it's about as close as you're gonna get to playing Neon Genesis Evangelion: The Game. Hopefully there'll be better long-range weapon control and a more polished Graphics Alchemic Drive written into the second season."

By its second week of sale in Japan, Robot Alchemic Drive had sold 17,888 units.
