Soulcalibur: Lost Swords was a free-to-play fighting game distributed through PlayStation Network. Released in 2014, the game is based on Soulcalibur V and is strictly single-player. It uses the same weapon-based fighting system from previous games; however, several of the gameplay mechanics are changed, simplified or otherwise removed. Similar to other free-to-play titles like Tekken Revolution, microtransactions are offered, some of which remove the playtime limit of the game. (wikipedia.org)
