The story takes place in 1044 BC, and starts out with the Emperor setting fire to himself when his land is invaded, and with his grand wizard then opening up a portal between the realms which allows all sorts of hideous monsters to break through and cause chaos. It's got an unusual setting and some intriguing combat moves but this isn't enough to save it from being largely tedious.
Blade & Sword is a Chinese Diablo-style action RPG which is far worse than its inspiration and similar titles like the Incredible Adventures of Van Helsing and which remains little more than a curio that only diehard genre fans will get any fun out of.
