Sega revved up the Yakuza 4 promotion machine with an action packed trailer. Before you watch it you might want to read up on the three new characters. This trailer jumps straight to Saejima carrying a gun his mouth without introducing him.
Sega also shared the stylish Yakuza 4 box art for North America. The Japanese box art is on the right for comparison. Yakuza 4 comes out in the West in spring 2011.
