Mega Man X6

Mega Man X6, known as Rockman X6 (ロックマンX6) in Japan, is the sixth game in the Mega Man X series and the final title in the series to be released for the Sony PlayStation. Both Mega Man X5 and Mega Man X6 were released after the launch of the PlayStation 2, so after the development and release of Mega Man X6, Capcom made the transition to the PlayStation 2. Mega Man X6 was developed and released on the original PlayStation mainly to reach out to a broader audience. The game was later re-released as part of the Mega Man X Collection.

Series artist and producer Keiji Inafune was not involved in the games production, as he had originally intended for the series to end with Zero's death in Mega Man X5. As such, X6 caused a change of plans in the Mega Man X series, since it was originally intended to have Zero resurrected in the Mega Man Zero series.

Story
Three weeks after the crash of the Eurasia colony in Mega Man X5, the Earth's surface is badly damaged, and humans have been forced to live underground to survive from the pollution. Reploids have been sent to the surface to attempt to make it livable once again. There was no trace of Mavericks for some days, and the Maverick Hunters help cleaning up the world. Gate, a Reploid scientist who was once a colleague of Alia, stumbles upon the crash site of Eurasia, finding something unusual. After that, Gate became mad and a strange set of Maverick outbreaks occurs, and when X is called to stop a giant Mechaniloid, he sees a purple-like figure that resembles Zero. Around the same time, a powerful Reploid named High Max appears and claims to be investigating the Zero Nightmare, and they fight. High Max, however, proves to be too strong and X cannot damage him with his X-Buster.

A Reploid scientist named Isoc makes a announcement saying that the ghost of Zero, Zero Nightmare, is behind the new Nightmare Phenomena. He sends eight Reploids to investigate areas with high jamming suspected to be infected by the Nightmare to discover the mystery surrounding it and delete Zero's ghost, with High Max leading the mission. Isoc also ask for volunteers to help them. X goes off to the suspected areas to investigate the Nightmare, defeat the Mavericks, and rescue the Reploids that volunteered to help.

During his mission, X fights against the Zero Nightmare and finds the real Zero, who was believed to have been destroyed after the last encounter with Sigma. Signas is reluctant to ask Zero's help as he had just return, but due to the crisis, Zero helps X in the mission.

After defeating the Mavericks, the Maverick Hunters discover Gate was behind the Nightmare Virus. Gate is impressed with the abilities of X and Zero, and challenges the Hunters to a duel, revealing them the location of his hidden laboratory. In his laboratory, Gate also reveals he was able to create the Nightmare and High Max by analyzing Zero's DNA, which he found in Eurasia's crash site. X and Zero defeat High Max and Gate; Isoc was later found unconscious in a similar way to the Erasure Incident (mentioned by Alia when playing as X). Upon Gate's defeat, Gate reveals he had revived Sigma. Sigma states that he didn't need his help to revive, attacks Gate and retreats. X and Zero rush to stop the partially-reconstructed Sigma and battle him, and although he was not fully complete, he puts up a good fight. In the end, the Hunters prove victorious, defeating Sigma and removing Gate's body from the wreckage of his lab to attempt to repair him.

Gameplay
Mega Man X6 is identical to its predecessor in terms of general gameplay, traversing through dangerous terrain while defeating a legion of enemies throughout the way. Unlike the previous two games, the player starts out the game as X. However, X has changed considerably. While he again starts out with the Falcon Armor, most of its special abilities have been lost, but for a trade in, he can use Zero's Z-Saber as an alternate weapon, although he wields it with less skill and thus can only use single swings. Some areas contain a portal which X can go through. Should he enter one, he will enter an extra area which will lead to a battle with a boss version of Zero known as the Zero Nightmare. Winning this battle will reveal the real Zero and unlock him as a playable character. While he has not changed much, his Z-Saber has a somewhat longer reach and its appearance has changed into a straight sword. His Z-Buster also fires faster but can only be fired on the ground as usual.

X can gain more than two armors as usual though they must be assembled before they can be utilized: The Blade Armor, which enhances X's melee potential with the Z-Saber and the Shadow Armor which ups his maneuverability and grants him immunity to spikes.

In each stage except the last one exists the Nightmare Phenomenon, strange helix-based enemies that, although weak, can prove troublesome. Though they have no sufficient means of attack, they will often attempt to infect Rescuable Reploids which the player must save to obtain bonuses and upgrades and turn them into enemies. Defeating a Nightmare will yield a Nightmare Soul which can be used to upgrade how many parts can be equipped to a character. A Soul must be retrieved quickly before the Nightmare revives itself where it will not yield it a second time.

Trivia

 * In gameplay, Mega Man X6 is the only game where it is impossible to acquire both the Ultimate Armor and Zero's black armor in one playthrough (or save file) without using external cheats. X4 also shares a similar situation, although it's only because X and Zero are playable separately.


 * This is one of the few games that doesn't feature Sigma as the main villain, a first in the X series. That honor goes to Gate, though Sigma was still included as the final boss.


 * This game is dreaded by some fans because of the nightmare system, Gate's stages requiring certain types of parts and/or armors to pass and the overall level design of the stages that makes taking damage mandatory to proceed.
 * This is the first game in which the Reploids in the game could be corrupted, collected, or be missing. It was also the first to mention they could give X and Zero upgrades.


 * Zero's ending in the game is supposedly the true ending of the Mega Man X series (however, the ending was originally planned to be one game earlier). It was never officially stated when this ending takes place, allowing three sequels (Mega Man X7, Mega Man X8, and Mega Man X: Command Mission) to be made so far.


 * This is the first game in the X series where most of the eight Maverick's names were not differentiated from the Japanese release for the US release.


 * The Reploids that are able to be rescued in Blizzard Wolfang's stage share the same names of characters from other Capcom franchises such as Street Fighter, Resident Evil, and Devil May Cry. (Ryu, Ken, Leon, Dante, etc.)


 * This and X3 are the only X series games in which X and Zero can use both a Buster and Saber.


 * Due to a continuity error, the games intro states that the events of Mega Man X6 took place three weeks after the events of Mega Man X5, whereas in X's ending of X5 (if Zero does not become Maverick), it is stated that it took place three years later.


 * This game is known to have a somewhat low-quality translation. One example is Alia saying that, "A high jump part will be help.", at the beginning of Blizzard Wolfang's stage. A retranslation was planned for the Mega Man X Collection, but the changes were dropped.


 * Interestingly, the area where the game's ending takes place seems to be similar to the area Zero was discovered if the player defeated the Zero Nightmare.


 * Oddly, this game has the most themes for the bosses in Gate's Laboratory stages.


 * This game and Mega Man X5 are the only games in the entire series which doesn't fully require the player to defeat all of the eight mavericks to unlock the final stages.


 * If one looks very carefully at the opening cinema of this game, one will see a detailed script between Sigma and Dynamo before the opening scene of Mega Man X5, describing Sigma's observation of the Colony to Dynamo, to the battle between X and Zero, and the aftermath of the Earth Crisis.


 * Like Mega Man X2, there seems to be a translation error where X discovered Zero. In the english version, Zero states that he "hid himself while trying to repair himself", whereas in the original Japanese version, he said no such thing, but compared his survival to X's.


 * From this game to Mega Man X8, Zero has a rolling double-jump present by default.


 * If one defeats High Max in the Nightmare Area (easily done with X's Ultimate Armor), the way to Gate's Laboratory will open. This means one can effectively reach the end of the game without fighting a single Maverick Boss.
