The collection, developed and published by Capcom, launched on Nintendo Switch in April 2023 and compiles the classic Mega Man Battle Network series that originally debuted on the Game Boy Advance.
Capcom confirmed the eShop download cards will be available at electronic retailers and convenience stores across Japan beginning March 27, 2023.
The cards are designed as tribute pieces, with artwork that reimagines the collection’s box art as a Game Boy Advance cartridge to recall the series’ original GBA home.
Retail options include a card for the full Mega Man Battle Network Legacy Collection as well as separate eShop download cards for Volume 1 and Volume 2.
The company said these separate-volume cards will carry similar Game Boy Advance–style cartridge artwork to match the full-collection design.
As part of a limited retail campaign, Capcom is partnering with major convenience chains 7-Eleven and Lawson.
Customers who purchase the download cards at participating 7-Eleven and Lawson stores will receive a special in-game Battle Chip Set containing three chips selected by Mega Man Battle Network scenario writer Masakazu Eguchi.
Capcom also announced a referral element to the promotion: players who refer friends to the campaign can obtain additional Battle Chip Sets as part of the offer.
The Mega Man Battle Network Legacy Collection brings the tactical action-RPG entries of the Battle Network subseries to modern platforms, and the retail eShop cards give collectors a physical keepsake tied to the series’ GBA origins.
For collectors and fans in Japan, the GBA cartridge–inspired design and the limited Battle Chip Set promotion create a clear retail incentive ahead of the collection’s April 2023 release on Nintendo Switch.
Capcom’s announcement and the Japan-exclusive retail details apply specifically to these eShop download card releases; the collection itself is available digitally on Nintendo Switch and other platforms in line with Capcom’s April 2023 launch schedule.
