This is the first thirty minutes of Toukiden for the Playstation Vita. It is a hunting action game from Williams/Tecmo Koei and the full version is much improved over the demo that was released a couple of months ago.
Toukiden is a more classical-Japanese take on Monster Hunter and other games in the Hunting genre. In it's first week on sale in Japan, the Vita version outsold Soul Sacrifice's first week -- and that doesn't even include the PSP version. It is currently still sold out at many retailers nationwide.
Toukiden is due for release in the West at some point in the future -- hopefully 2013.
