The fine individuals who have brought you C&C Tiberian Dawn Redux and Tiberian Sun Redux for CnC Zero Hour, have decided to switch over to CnC 3 to give you a more Tiberian Sun themed mod then they could on Generals Zero Hour. The mod will feature all of the Original Tiberian Sun and Firestorm units, together with new never seen before Forgotten units and structures, GDI and Nod Tiberian Dawn Timeline units and structures you can capture on the battlefield or even if you want play as them, and remove those Hightech egg-heads from the battlefield. With all this extra firepower a new faction have arrived, little to none information is available at the time for what there purpose is in this war, but we will find out soon.
For sometime, GDI had been developing a mobile platform capable of projecting sonic energy for its use as a weapon. This eventually led to the creation of the Disruptor with a prototype being developed by the time of the Second Tiberium War. Once Kane had emerged from his supposed death of the First Tiberium War, he charged the Brotherhood of Nod to acquire the crystals used in the Disruptor design. Nod managed to capture these crystals from GDI's Hammerfest Base. However, a task force led by Michael McNeil managed to prevent the crystal from being taken by Nod forces in the following mission.
After the Firestorm Crisis, as with many of GDI's experimental technologies, the production of the Disruptor ceased and it was phased out of the assembly line as a military vehicle. However, many of the elements of the design such as the usage of harmonic resonance was greatly expanded upon and the use of the Disruptor helped pioneer GDI's research into that field of science. This not only let to the development of powerful stationary sonic emitters but also more mobile versions of the technology such as the Shatterers and Zone Shatterers which saw deployment in the Third Tiberium War.
By the Ascension Conflict, Tiberium had proliferated to a level where Sonic weaponry was ineffective against them, leading to the abandonment of Sonic technology altogether. However, GDI continued to field the technology for combat, in the form of the Shockwave hovercraft.
The description is true, but only if you follow EA's C&C lore :P
