Utawarerumono Prelude To The Fallen Build 6150670 ((exclusive)) -

Build 6150670 was a fragile miracle. In prior builds—6149982, 6149991, 6150017—the world had decayed. Memory leaks flooded the lowlands, turning them to permanent marsh. Physics glitches caused avalanches. In one forgotten build, the moon failed to rise. The system had crashed entirely during the battle of the Frontier, leaving the hero frozen mid-swing for a subjective eternity.

And the mask—Artifact U-01, the Master Key, the first bug and the last prayer—cracked. Utawarerumono Prelude to the Fallen Build 6150670
