Mega Man Zero/ZX Legacy Collection

Mega Man Zero/ZX Legacy Collection, known as Rockman Zero & ZX Double Hero Collection (ロックマン ゼロ&ゼクス ダブルヒーローコレクション) in Japan, is the upcoming fifth game in the Mega Man Legacy Collection series, collecting the Mega Man Zero and Mega Man ZX series produced by Capcom and Inti Creates. It will contain the four games from the Zero series and the two games of the ZX series along with additional content and gameplay modes for both series. It was officially announced on August 27, 2019, and is set for release on February 25, 2020 worldwide for the Nintendo Switch, PlayStation 4, Xbox One and PC (via Steam).

Games included
The collection includes the Zero and ZX series in their entirety:
 * Mega Man Zero
 * Mega Man Zero 2
 * Mega Man Zero 3
 * Mega Man Zero 4
 * Mega Man ZX
 * Mega Man ZX Advent

Gameplay Changes

 * The dual-screen controls from Mega Man ZX and Mega Man ZX Advent are back. As the game has been modified to fit everything onto a single screen, the players now have the option to position these controls to where they prefer on the screen in seven separate configurations.
 * Akin to Mega Man X Legacy Collection 1 and 2's Rookie Hunter Mode, the game presents a Casual Scenario Mode, which, among other changes, prevents players from dying upon falling into bottomless pits.
 * This is the second Zero series release to offer easier gameplay for inexperienced players, the first was Easy Scenario from Mega Man Zero Collection.
 * The game presents a new Save-Assist feature, which puts extra checkpoints that function as save states along stages. This allows players to retry and practice difficult sections and bosses, which functions similar to the save feature from Mega Man Legacy Collection (as well as the titles used in the Nintendo 3DS/Wii U Virtual Console releases) of saving whenever the player wishes to in any part of the stage.
 * The Casual Scenario Mode and the Save-Assist feature can be turned on or off independently of each other.
 * The game also presents the ability to toggle between the Original and 'Mastered' voice tracks for Mega Man ZX Advent.
 * A new link mode accessible from the main menu has been added for Mega Man ZX to mimic the Nintendo DS/Nintendo DS Lite's Dual Link feature from the original release which allows for players to face against the Mutos Reploid bosses from Zero 3 and Zero 4.
 * Much like with the previous Legacy Collection releases each game has its own wallpaper design which the player can switch through or turn off. Similar to Mega Man Legacy Collection 2 each game has multiple wallpaper, which is two for each game. Also similar to Mega Man X Legacy Collection 1 and 2, any type of wallpaper can be selected from any of the games regardless of game, along with the wallpaper from Z Chaser and a hidden unlockable wallpaper.
 * However the wallpaper from Mega Man ZX and Mega Man ZX Advent can be further affected not just be the size of the screen, but also the type the player uses to position the dual-screen controls for the respective game.

Extras

 * An illustration gallery and music player in the same style as the one from both Mega Man X Legacy Collection titles.
 * This is the second Zero series title to include an art gallery as an extra, after the previous collection game Mega Man Zero Collection.
 * A new "Z Chaser" mode. This mode will have a difficulty level setting from lowest to highest: B, A, S, Z, and ZZ and is a time trial-type challenge.
 * It will be available on three special modes: "Single Chaser" (single player challenge), "Double Chaser" (2-player challenge), and "World Record Chaser" (where the time of the best players are recorded and similar to the past Legacy Collections and Mega Man 11, their performance can be viewed by other players).
 * This mode will have 12 challenges in total, 2 for each game.
 * Much like with Mega Man X through Mega Man X6 in the Mega Man X Legacy Collection 1 and 2 releases, graphics in this collection for the Zero and ZX games can also be adjusted with HD filters.

Pre-Order Bonus
Players who pre-order this collection can get free DLC for ten new music tracks; six of them being remixes from the games included (one for each game) and four bonus selections, which are only accessible in the Music Player.

Achievements
Similar to the Hunter Medals from the Mega Man X Legacy Collection 1 and 2, ZZ Cards can be collected by completing certain feats within the games, which for most systems excluding the Switch can also award the player with PSN Trophies/Achievement Points.

Much like with previous PlayStation 4 releases that began with the Mega Man X Legacy Collection series dual-release, collecting all the PSN trophies can earn players the Platinum trophy which is only available for this version.

Trivia

 * This marks the first time mainline games from two different Mega Man series are included on the same disc/cartridge as a collection.
 * This also marks the first time that Mega Man ZX and Mega Man ZX Advent have been re-released.
 * Additionally, this is the first collection to include two different Mega Man series in their entirety (as of the collection's release) and the first Legacy Collection release to have a single game release for a series instead of it being divided into two separate games.
 * While Mega Man X Collection did include Mega Man: Battle & Chase from the classic Mega Man series, the latter is a spin-off and was included as a bonus as opposed to being a main component of the collection.
 * This is the first time the Zero and ZX series will be released on a different platform that is not from Nintendo; the Zero series were originally released on the Gameboy Advance and later on the Nintendo DS in the form of Mega Man Zero Collection as well as the Wii U as part of the Nintendo e-Shop's Virtual Console, and the ZX series was originally released on the Nintendo DS.
 * Like Mega Man X Legacy Collection and X Legacy Collection 2, Zero/ZX Legacy Collection is rated T for Teen when their original releases were rated E for Everyone, though Mega Man ZX Advent was originally rated E10+.
