Samurai Warriors 4 unsheaths for launch

Tecmo Koei has put up a load of art and a new trailer on the official site for this week's launch of Samurai Warriors 4. The game supports cross save between the PS4, PS3 and Vita versions, and looks like another highly stylish and effective slice of feudal Japan.

With a huge roster of characters, massive battles and detailed graphics, it'll be interesting to see how the Vita version stands up.
