As already revealed by Famitsu, Yuusha 30 lets players save the world from evil "Demon Kings" thirty seconds at a time. It's a role-playing game. It's an action game. It's a real-time strategy game. And it's a shooting game (read: shmup!). All of it delivered in thirty second chunks.
Marvelous' first trailer for the game sure looks melodramatic, but not without its charms. Cross your fingers (in 30 second intervals) for a localized release.
