Since the early '90s, it's been easy to find games from SNK's Samurai Shodown 2D fighting series in arcades on both sides of the Pacific. The games are known for fast action and colorful characters, each of whom wields a different martial arts weapon. Compiled for a 2009 release, Samurai Shodown Anthology for PSP includes pitch-perfect emulations of all six Samurai Shodown arcade games to date, including Samurai Shodown 6, previously unavailable in North America. By playing the games, players can unlock additional content, such as artwork and original promotional materials.
