A 2014 action game from Spark Unlimited that reimagines Ninja Gaiden with a zombie-themed protagonist and arcade-style combat.

YAIBA is a licensed IP property with modest residual revenue and a split fanbase that largely rejected its departure from core Ninja Gaiden design. The game has cycled through a single discount in the past year and maintains a mid-tier price point despite declining sentiment. Revival is unlikely given the studio's defunct status and the franchise's return to strength under Team Ninja; the realistic play is licensing evaluation or catalog acquisition only if bundled with other Koei Tecmo titles. Most realistic play: licensing.

• Risk: Ninja Gaiden IP owned by Koei Tecmo; any revival or re-release requires publisher sign-off and likely renegotiation of original development terms.
• Risk: Community consensus frames the game as a failed experiment that alienated the franchise fanbase; sentiment has declined 7 points in recent months despite minimal update activity.
• Risk: Developer studio (Spark Unlimited) is defunct; no ongoing support, patching, or porting capability exists in-house.
