In 2023, Mega Man Battle Network Legacy Collection[d] was released, which include all six main games from the Mega Man Battle Network series, including both versions of later titles, for a total of 10 games split between two releases.

The original Mega Man Legacy Collection was released on August 25, 2015, for Nintendo 3DS, PlayStation 4, Windows, and Xbox One.

[4] A sequel, titled Mega Man Legacy Collection 2, was developed by Capcom and released on August 8, 2017, for PlayStation 4, Windows, and Xbox One.

A "Challenges" mode offers several time-based missions for players to attempt, such as completing a certain goal within a stage or defeating multiple bosses.

[9] Legacy Collection also includes a Database mode similar to that of the earlier Rockman Complete Works releases, which lists character profiles.

On April 10, 2018, as part of the Mega Man X 25th Anniversary celebration, it was revealed that the eight games would be split between two volumes.

The secret codes from the original releases of the PS1 titles and X8 return for this collection, with the buttons required for some of them being based on the controller of the system used.

The collections also feature an extensive multimedia gallery including original trailers, merchandise images, concept art for all eight games, and the "Day of Sigma" animated short from Mega Man: Maverick Hunter X.

[12] Additionally, a new "Link Mode" was added for ZX to recreate the original release's ability to connect to Zero 3 and Zero 4 via the DS's GBA slot; by choosing which game to link to before starting play, players can battle four additional bosses from each game,[13] and the modification cards that were unlocked with the Nintendo e-Reader[14] in the original Japanese release of Zero 3 are included, which are listed in the collection as "ZZ Cards" and are unlocked in groups by completing certain achievements.

[15] On June 28, 2022, during a Nintendo Direct, Capcom announced Mega Man Battle Network Legacy Collection, released on April 14, 2023.

[20] The game's menu features an interactive MegaMan.EXE that reacts to the player's choices, reprised by his MegaMan NT Warrior actors Akiko Kimura in Japanese and Andrew Francis in English.

[21] Players who pre-ordered the game received a DLC pack containing two alternate skins for MegaMan.EXE on the menu (one skin per volume), as well as four additional remixed tracks for the game's music player (two tracks per volume); the pre-order content was later made available for purchase on June 27, 2023.
