And no we’re not talking about the side-scrolling spiritual successor also developed by Opus Studio. Famitsu has news about sequel to Half-Minute Hero called Yuusha 30 Second for PSP.
Aside from the clever title we don’t have much information… yet. Scans haven’t leaked out, but reports from message boards peg Marvelous as the publisher.
Update: Unconfirmed details from message boards claim Yuusha 30 Second has a four player battle mode and edit mode.
