Revision 30962614 of "Electronic Video Agent" on enwiki

The '''Electronic Video Agent''', or '''EVA''', is a [[fictional]] [[artificial intelligence]] featured in the [[science fiction]] [[real-time strategy]] [[computer game]] series [[Command & Conquer]]. Its counterpart is NOD's [[Computer Assisted Biologically Augmented Lifeform|CABAL]]. Other examples of EVA-like technology exist throughout the various series as well.

While EVA is often used in the game universe as a generic term for all battlefield [[command and control]] systems, it actually refers to a specific device, a combined strategic artificial intelligence, [[military espionage|intelligence gathering]] tool, communication system and [[console]] interface, giving field commanders an [[omniscient]] view of the [[theater (warfare)|operational theatre]]. This technology allows the player to give commands to individual units on the battefield. 

In the Command and Conquer storyline, the EVA technology is developed in the [[1950s]] computer revolution during the (fictional) war between the [[Europe]]an powers and the [[Soviet Union]]. The voice for the interface, which remained the same whether playing the Allies or the Soviets, is male. 
Later, at the beginning of the first Tiberian war, the EVA unit is introduced and the voice is that of a female.

Though the Red Alert and Command and Conquer series divert at this point, EVA and its equivalent are found in both series of games. It is also possible that an EVA-like equivalent exists in the ''Command and Conquer: Generals'' series as well, given that the controls between the three series are similair.


== Command and Conquer Series: ==
In the Command and Conquer series, by the first Tiberian War in [[1993]] EVA is the routine method of battlefield control and is a limited [[artificial intelligence]]. By the second Tiberian War in the [[2030s]], EVA is fully developed, with highly sophisticated [[natural language processing]] abilities and intelligent thought sufficient to make complex [[strategy|strategic]] and [[tactical]] decisions traditionally assigned to experienced commanders.

The [[original]] and [[authentic]] version of EVA is the exclusive property of the [[United Nations]], and is in use by the executive and military arm of the [[United Nations Security Council]], the [[Global Defense Initiative]]. However, additional [[software piracy|pirated]] versions are known to exist. In the the first Tiberian War, the [[Brotherhood of Nod]] uses such a pirated version of EVA. The Brotherhood again obtains a copy of EVA during the second Tiberian War when NOD's (equivalent) device, the [[Computer Assisted Biologically Augmented Lifeform]], goes rogue. It is also possible, given their level of organization, that ''The Forgotten'' posess a copy of EVA to coordinate their defense efforts; but this has never been substantiated.


== Other 'Conquer' Series: ==
In ''Command and Conquer: Red Alert 2'', as well as the expansion pack, ''Yuri's Revenge'', the player in the role of one of the three faction's generals is assisted by an aide. The Allies' aide is named Lieutenant Eva. The Soviet aide is Comrade Sofia. Yuri's faction has an unnamed acolyte performing this role.
Eva and her counterparts perform similar duties to the EVA system, acting as a vocal interface for the player. This reliance on a human coordinator suggests that the version of the EVA-like technology in the Red Alert storyline is not yet as advanced as that found in the Tiberian series; despite the fact that the Second Soviet War actually occurs in the early [2000s] as opposed to the [1990s]. 

''Command and Conquer: Generals'', and its expansion, ''Zero Hour'', have no direct link to the other Command and Conquer games. However, players in the role of the three faction's generals have the same minute control over their units as in other Command and Conquer games. While this technology is not EVA per se it is clearly an equivalent to justify the same feel between the different series.
