Mega Man Xtreme 2

Mega Man Xtreme 2, known in Japan as Rockman X2: Soul Eraser (ロックマンＸ２ ソウルイレイザー), is the second and last X game on the Game Boy Color, released in 2001. The story of the game takes place between Mega Man X3 and Mega Man X4. Unlike the previous game, Mega Man Xtreme, this game doesn't work in the original Game Boy, being only for Game Boy Color.

Story
All over the world Reploids are having their programs (memories and personalities) suddenly erased, becoming like hollow shells. This phenomenon was named "Erasure". One day, the readings of Reploids in "Laguz Island" in the Southern Ocean had instantly vanished, and the Maverick Hunters X and Zero received the orders to investigate the island to attempt to determine what is going on and who is behind the soul erasures.

Game modes
X Mission and Zero Mission: In the beginning, only those two modes are available. In X Mission, the four mavericks are Launch Octopus, Volt Catfish, Neon Tiger and Flame Mammoth. These mavericks can only be fought as X. After the four mavericks are beaten, then you can enter the final stages and you are given the ability to switch between X and Zero at any time by going into the pause menu or pressing select. Zero has all of his armour parts, but can't use any special weapons. In the last level, the hunters split up again; X takes on Berkana and Zero takes Gareth. In Zero Mission, the player controls Zero, who must fight Overdrive Ostrich, Wire Sponge, Tunnel Rhino and Blast Hornet. In the final levels, X becomes playable again. In the very last level, the beginning of the level is the same but after the point where the hunters split, it's a different level with a different final boss.

After completing one of these modes, the player can save to continue the other character's mode, starting with the weapons from the bosses of the first mode chosen and any remaining DNA Souls. Like before, the character from the other mode can't use Special Weapons.

Extreme Mode: After completing the two previous modes, this mode will be unlocked. It can also be unlocked by buying it for 2000 DNA Souls. Both characters are playable from the beginning, and all eight Mavericks from both modes will appear. However, only the character that defeats the boss will obtain his weapon, leaving the player to choose which weapons each character will obtain. In the level where only one character is playable, which path you go depends on who you are playing as when the cutscene comes on and the hunters split up. After this level, you got to the true final level of the game and both characters are playable again. This level has a rematch with the eight Mavericks, a fight against Sigma, and a different ending.

Boss Attack Mode: This mode is unlocked after completing Extreme Mode, or by buying it for 2000 DNA Souls. It is a time attack against bosses. The player can choose between two paths. The right one is a fight against the eight Mavericks from this game, and the left one against the eight bosses from Mega Man Xtreme. Both X and Zero can use all eight weapons and all parts are available to them, but they don't have armor upgrades and Sub-Tanks.

Trivia

 * This is one of two instances (the second one a secret in X5) in the X series that Dr. Light gives upgrades to Zero's armor.
 * The "Erasure Incident" is mentioned in part of the dialogue of Mega Man X6 (Specifically, when X is looking at Isoc's blank remains).
 * The "Reploid Research Laboratory" is called "Reploid Research Lavatory" in the first scene of the game.
 * All speeches have a quotation mark in the beginning, but none in the end of the quote.
 * If X's Giga Attack is used while he is on ladder, a glitch will occur.
 * Part of the gameplay involves switching between the two playable characters, apparently a precursor to the feature seen from Mega Man X7 onwards.
 * If the player hold the Select button while choosing the Boss Attack mode, X and Zero will start this mode with complete armor.
 * A glitch will also occur if Zero uses Tri-Thunder repeatedly on Launch Octopus. This will cause Zero to be stuck in one place and will require a reset of the game unless the player is able to defeat Launch Octopus, however there will be glitched graphics.
 * In the final level of Zero Mission, Iris contacts Zero and warns him that he's fallen into their trap. She does not, however, contact X.
 * This is the first Mega Man X game that shows a Navigator.
 * While Iris is shown in the game, no one knows how Mega Man X and Zero met her.
