In the spirit of official Mega Man Battle Network/Boktai crossovers of yore, fan projects Mega Man Battle Network 3D and the Boktai-inspired are Kura5 teaming up for a ghoulish collaboration.
"Special Collaboration with Kura5! Kura5 is a fan game based on Konami's Boktai series where two strangers harness the powers of light and darkness in order to slay the Immortal menace! Mega Man Battle Network and Boktai have a history of cross-overs dating all the way to Mega Man Battle Network 4, so in the spirit of those cross-overs we'll be carrying on the torch.
This cross-over will be featured in special missions in MMBN3D and a sidequest in Kura5!"
