Soulcalibur: Lost Swords is officially available on the PlayStation 3 starting today. If the PSN has updated in your area, then the download is ready to be... downloaded.
Lost Swords is exclusive to the PlayStation 3 and is free on the PlayStation Network. It's a single-player, one-on-one fighting game. Every battle you compete in draws from an in-game currency of sorts. Due to this, it is sort of like a F2P game in that once you are out of in-game currency you'll have to either wait a while or buy more with real money.
I'll have a review posted later this week.
