A second trademark, caught by Siliconera, has been made for Soulcalibur: Unbreakable Soul, which Namco Bandai originally registered in the US on October 11.
Curiously, the trademark was for use with video games as well as computer game networks, suggesting that it will be an online title unlike Soulcalibur: Lost Swords, which is a free-to-play single-player title. This resurgence in this fighting series also arrives with a port of Soulcalibur II.
We can only hope that Unbreakable Soul is a full installment to the franchise, or perhaps a fully upgraded Soulcalibur V.
