Soul Calibur: Lost Swords, the free-to-play entry into the long-running Bandai Namco fighting series, is now available to download on PlayStation 3 via PSN. It's a single-player focussed fighter (that's right, no versus) that will take fans of the franchise back to earlier releases where there was increased emphasis on solo adventures and customised characters. A trio of new trailers have landed alongside the announcement, and you can check them all out below.
