Namco Bandai is on a free-to-play kick of late. Tekken Revolution came out for PlayStation Network over the summer; Ridge Racer Driftopia is currently in Early Access for Steam and coming to PlayStation Network as well; and Ace Combat: Infinity will take flight later this year.

Today, the Japanese publication Famitsu revealed the company has another free-to-play project in the works, this time for the Soul Calibur series. The weapons-based fighting game will get a new chapter called Lost Swords, set for release on PlayStation 3.

Not many details were provided, but Lost Swords is expected to have a similar system to Tekken Revolution, where a handful of fighters are available at first, with more that can be unlocked over the course of the game.

This news follows Namco's announcement of Soul Calibur II HD Online, which will release for PlayStation Network and Xbox Live Arcade later this year. That game won't be free-to-play, but will include a number of popular fighters, including the return of Tekken's Heihachi and comic book hero Spawn, from the PlayStation 2 and Xbox versions of the game.

Look for more details on Lost Swords in the months ahead. In the meantime, the trailer for Soul Calibur II HD Online is below, to give you an idea what to expect.
