Tiberium

Tiberium, known as Ichor to the Scrin, is a fictional substance that is central to the plot of much of the Command & Conquer series of real-time strategy computer games. Within each title set in the Tiberium story arc (Tiberian Dawn, Tiberian Sun, Renegade, Tiberium Wars, Tiberian Twilight, and their expansion packs), the Tiberium crystals represent both the tools and spoils of war and are used by players to purchase new units and buildings, with each of the series' factions either directly or indirectly battling for control over the crystals. Tiberium has extraterrestrial origins and comes in a variety of forms, mostly the common green crystal but also the more rare blue crystals, the extremely rare red crystals, and in "veins". It was also demonstrated in a liquid form by the time of Tiberium Wars. Parts of the chemical composition of tiberium remain unknown.

Tiberium is presented as a double-edged sword within the context of the story arc of the respective video games. While it is the greatest mineral resource ever encountered, conveniently gathering many potent elements into an easily harvestable form, it also brings with it considerable hazards: areas rich with the rapidly spreading Tiberium substance are eventually exhausted of their native ecosystems, and become too toxic to support normal carbon-based life. In the context of the gameplay, Tiberium can also be seen this way with its obvious tactical advantage as a resource, and its destructive effect on infantry, sometimes transmuting them into destructive "Visceroids".

List of canceled Command & Conquer games

Over the years, several video games in the Command & Conquer franchise began development, but were eventually canceled. Command & Conquer: Renegade 2 and Command & Conquer: Continuum were both in development by Westwood Studios before being canceled due to Electronic Arts' closure of Westwood Studios in 2003. Tiberian Incursion, the sequel to Tiberian Sun was also in early stages of development, but was put on hold until some of its concepts were reused in Tiberium Wars. Tiberium was being developed by EA Los Angeles before it was canceled due to quality concerns.

Command & Conquer: Renegade 2

Command & Conquer: Renegade 2 was to be another first-person shooter game using an updated version of the "Westwood 3D" engine, used in Command & Conquer: Renegade. Renegade 2 had two build versions: The first version of Renegade 2, was drafted as a connection to Command & Conquer from Red Alert 2. However, this was scrapped in favour of a Red Alert 2 based FPS that took place in the post Yuri's Revenge world. The storyline was about a rogue Soviet commander attacking America to avenge the honour of Premier Romanov (the commander was a Romanov). Most units designed were based on Red Alert 2 styles, however the Allied Light Tank and Soviet Hind Gunship were included, units which only appeared in Red Alert.
