EGM: "Though Hayashi and co-executive producer Keiji Inafune (of Mega Man fame) deny any influence from Suda51′s Lollipop Chainsaw or Shinji Mikami’s God Hand—Inafune likens Yaiba more to his own Dead Rising—I felt a strong resemblance to those two over-the-top action epics during my hands-on time at E3. Sure, part of it was defeating shambling zombie hordes via colorful combos, but I also felt a connection via the game’s silly, sometimes-vulgar humor. At one point, Yaiba needed to destroy a panties factory, complete with fishnet-clad legs on the roof. His solution? Have a zombie drive a truck…right in between those legs. According to Hayashi, the American developers at Spark Unlimited are behind a lot of the humor in the game, and right now, it seems rather hit-or-miss."
