G-Darius (Gダライアス Jī-Daraiasu) is a shoot'em up arcade game, released by Taito in 1997. It is the fourth arcade installment of the Darius series and the first in the series to feature three-dimensional polygonal graphics.
Much like previous installments in the Darius series, G-Darius is a horizontally scrolling shoot'em up. While the game features three-dimensional polygonal graphics, the gameplay remains two-dimensional. The player controls a spaceship named the Silver Hawk and must battle enemies and avoid obstacles throughout the game's stages (referred to as "zones" in the game). The ship is armed with forward-firing missiles, small aerial bombs and a protective force field. These can be upgraded by power-ups, in the form of large orbs, that are dropped by specially-colored enemies when they are destroyed. When the player reaches the end of a zone, a boss appears, which must be defeated to proceed. Once the boss of a zone is destroyed, the player is given a choice of which zone to play next via a branching path.
