The game was released on November 25, 2014 for Microsoft Windows, OS X, Linux, PlayStation 3 and PlayStation 4, day later for Xbox 360 and Xbox One and in the middle of 2015 for iOS and Android.^[1][2][3][4] As the sequel to Geometry Wars: Retro Evolved 2, Geometry Wars 3: Dimensions is the first game in the series to be released on Sony platforms. It is the sixth installment in the Geometry Wars series and the first one developed after the creator of the series Bizarre Creations was shut down by Activision.

The player pilots a claw-shaped ship that can shoot independently of where it is pointing. The primary objective is to destroy a variety of enemy shapes which attempt to destroy the ship. Depending on the game mode, extra lives and extra supers can be collected upon achieving a certain number of points. Supers can be chosen before the game starts, and are expendable powerups that have extreme effects on the game, such as turrets that shoot enemies and a massive wave of bullets. In addition, several 'drones' may be selected to accompany the player to perform tasks, such as collecting geoms or firing on enemies.^[5]

Crucial to effective play is the score multiplier, which can be increased by collecting small green diamonds called "geoms". Skilled players may get the multiplier into the ten-thousands on occasions.^{[citation needed]}

Brett Makedonski from Destructoid gave the game a perfect score, praising the responsive shooting mechanics, distinct level-design of the adventure campaign, inclusion of various new modes, as well as a "classic mode", which has similar gameplay as its predecessor Retro Evolved 2. He stated that "Geometry Wars 3: Dimensions improves as much as possible while still staying true to the core of the franchise. That old game is still there, it's just unspeakably better now. It may have been past installments in the series that were billed as evolution, but Dimensions is where Geometry Wars truly evolved".^[17]

Christian Donlan from Eurogamer was more reserved in his praise, feeling the game wasn't up to par with its predecessors: "I'm not sure if Lucid really gets the mentality behind this series, and that makes for a perfectly serviceable shooter when the lineage requires something more".^[18]
