Mega Man X2

Mega Man X2, known as Rockman X2 (ロックマンX2) in Japan, is the second game in the Mega Man X series and was released for the Super Famicom/Super Nintendo in 1994. The game featured the same graphics as the first game, but was enhanced thanks to the use of the "Cx4" graphics chip (installed in the cartridge). The chip allowed for "semi-transparencies" and 3D effects.

Story
It has been six months since the destruction of Sigma and his Mavericks, but the Mavericks haven't been completely eliminated. A group of Mavericks was located in an abandoned production factory. The Maverick Hunters are mobilized, under X's command, to destroys the Mavericks in the factory, but the plot thickens. A new Maverick uprising begins to develop under a group of Mavericks that identify themselves as the X-Hunters, and X is faced with a new wave of Mavericks to face. Dr. Cain tells X that he has no choice and must once again stop the chaos that was developing. However, the X-Hunters also had the pieces of Zero, X's former partner that had sacrificed himself in the previous game for the safety of X. X manages to collect them before they could reconstruct him and program him against X. He also manages to defeat the Mavericks and penetrate the X-Hunter's fortress at the North Pole, defeating Violen, Agile, and Serges, until a resurrected Sigma reveals himself. X finds Sigma with a copy of Zero that he constructed, but the real Zero (having just been repaired by Dr. Cain) blasts him away with his buster. X then fights Sigma and once again defeats him, restoring peace and order for a second time.

Secrets

 * Armor parts and Shoryuken.
 * In Bubble Crab, Crystal Snail, and Overdrive Ostrich's stages, there are hidden rooms that don't appear to be special. But if Silk Shot is charged up, it will attract a large amount of either weapon or energy refills. What kind the player get depends on the room, but it is a useful way to fill Sub Tanks. Bubble Crab's stage is the fastest for this, as the room is near the entrance, just below the gate that the Sea Canthller opens to pass. Slide down the wall on the left, and X will fall right in. The Helmet Part can reveals those areas.

Trivia

 * The Armor Part could be considered the first Giga Attack in the series, as it is identical to the others: it requires a gauge to be completely charged up to be executed, and it damages the entire screen, similar to the Falcon Armor's Giga Attack.
 * Although Zero doesn't become fully playable until two games later, he also uses his first Giga Attack in this game, when X fights him in the last stage.
 * This is one of the strange few cases in the entire Mega Man series in which the final battle takes place in an earlier stage (see Magna Centipede).
 * Mega Man X2 is the first game to give the players hints about Zero's past.
 * This is the first time in the series where one of the final boss' forms does not have a health bar. This was later repeated in Mega Man ZX Advent with Albert's Mechaniloid.
 * The map in the stage select screen will have changes reflecting the defeat of certain bosses. For example, the lava from Flame Stag's volcano base will cool down and harden, Wheel Gator's tank will be trashed after his defeat. Also, after defeating the bosses again in the North Pole base, selecting it on the stage select screen will show that it's been destroyed.
 * The sequence of stars at the ending is similar to that of Mega Man 7 at the ending.
 * Even though you go back to the X - Hunter's castle, you'll be in Magna Centipede's stage, but your fight with Sigma is below the room in where you fought Chop Register.
 * It is speculated that Serges (the so-called leader of the X-Hunters) was actually a reincarnation of Dr. Wily, who had his artificial intelligence placed inside the Reploid body of Serges, which would explain how he was familiar with Zero's design. However, Capcom has never given any official word on this.
