Halo E3 2000 trailer

300px|right At E3 2000 an early trailer for Halo: Combat Evolved was shown. It was called the Halo E3 2000 Trailer. It depicted events not in the final game.

A pair of Elites are depicted on patrol, watch a pair of Banshees fly away, and then are sniped by the Master Chief who has a different and more robotic voice. He then claims that a landing zone is clear, and a Pelican dropship flies in, putting down Marines (a squad comprised of Sergeant Stacker, Private Wang, and several unranked Marines: Geoff, Segure, McLees, and Laine) and a Warthog. They split into two teams, headed for the same destination. As they travel across Halo, they encounter native wildlife not in the final game, resembling Dinosaurs. The group with the Warthog (McLees, Segure, and Geoff), get to the target first, spotting six Elites, four Ghosts, a Wraith, and what looks like a Spectre. McLees and Geoff attract their attention, drawing the Wraith into range of Sigure's Warthog cannon, but McLees is killed by Needler rounds to the head and back. Stacker's group appears, flanking the Elites and killing all of them. They go in the Forerunner structure whil Geoff and Segure guard the door. The three marines proceed into an underground chamber where they are soon ambushed and massacred by more Elites, the only Covenant alien featured in the Trailer. One Elite in particular is depicted wielding an energy sword in one hand and a large Energy Shield on his other arm. It is possible that it was shrunken and transferred over to the Jackals in the Final game. Wang is killed by the Elite with the sword, and Laine is killed on the ramp back to the door. Stacker is killed urging the remaining marines to fall back. Segure covers the door while Geoff takes a Ghost and flies off. Segure fails to kill the Major Elite running to a Ghost to pursue Geoff, and is shot by three Minor Elites. A wounded McLees detonates a grenade to take out the Minors before they can fly off in the Spectre vehicle, destroying all the vehicles there.

The Major and two Banshees pursue Geoff and destroy his Ghost. Geoff is wounded, out of ammo, and about to be killed, when the Master Chief appears with an Energy Sword. The Chief then impales the Elite with the Energy Sword. Geoff is evacuated while the Master Chief tells him that his fight is just starting.

Bungie also made a comedic advertisment "demonstrating" the N Vidia GE-Force 2 GTS graphics card using the E3 engine to make the commercial. Link-

Noticeable Differences

 * Sound effects for the weapons differ significantly, as do the visual effects used during their firing. They make longer laser-like streaks and noises instead of the short-round plasma blasts.
 * Halo is depicted as having an assortment of natal and native wildlife.
 * The Banshees depicted have tail flaps that act as a rudder for aerial steering.
 * A Major Elite uses the Energy Sword to kill one of the Marines. However, that particular rank never uses the Sword in the final version. A Minor Elite was also seen wielding the Energy Sword.
 * The Assault Rifle used by the Marines appears to have a wood finish on various parts.
 * The Marines are depicted to be much more efficient in combat than the final version of the game would prove. Their armor and color of uniform differs slightly, and their rangefinder eyepiece is red, instead of green.
 * The Elite's design is slightly different in some scenes, where it has a lower jaw instead of the four mandibles. Some of them have mandibles.
 * There is an early version of what appears to be the Spectre. It seemingly was meant to be in the game also, but didn't make the cut until Halo 2 came out. This is probably where the Shade turret came from, as there is one planted on top of the Spectre.
 * Look very carefully at the Sniper Rifle the Master Chief was using in the beginning of the trailer. He was wielding the SRS99D-S2 AM Sniper Rifle, which was used later in Halo 3
 * The Master Chief uses an Energy Sword, which he isn't able to do until Halo 2, he has a robotic voice, and a radio antenna on his shoulder. When he is hit by enemy fire, his shields flicker blue instead of yellow.
 * The Elites don't seem to have any shields like they do in the final version of the game since Marines can easily take them down individually with an apparent lack of effort
 * The Elite's Energy Shield was like that of a Jackal's personal shield although larger.
 * The Elites also sound very different, with deep and rasping voices, and bear a noticeable resemblance to the noises made by the Flood in the final version.
 * The marines' warthog is armed with some kind of light artillery piece, and it is not a turret or rocket launcher. It may be an early version of the Gauss Cannon, which did not appear in the final cut of Halo. It is capable of knocking out a wraith in two shots, rather than the LAAG in the the shipping version. It also glows purple rather than yellow on the windshield and headlights.
 * The only Covenant in the trailer are Elites, no Grunts, Jackals, or Hunters.
 * The Needler's projectiles don't glow. They are more like an explosive version of the Brute Spiker.
 * The Elites hold the Plasma Rifle in a different way
 * The inside of the Pelican looks different.
 * Some of the energy blasts seem to be from Covenant Carbines
 * Cortana is voiced by Joe Staten
 * Furthermore you must notice that the red Elite speaking says: "Your destruction is the will of the Gods. And we are their instruments." Truth says this in one of the first cutscenes in Halo 3. (First cutscene on "Crow's Nest", only difference is that he says "And I? I am their instrument." Instead of "And we are their instruments."
 * The trailer plays a track which ended up being the main theme for Halo 3.
 * The grenade which the marine activated to kill the elite looks a lot more stronger than the final version one.
 * The Pelican in the trailer does not use the NATO phonetic Alphabet in its registration (ie: E419), instead it it just the number 79.
