The Taiwanese software house International Game System is known for its Knights of Valour series of side scrolling beat'em up arcade games, and back at Tokyo Game Show it announced the new installment of the franchise, Sangoku Senki: Knights of Valour, coming exclusively for PS4 as a free to play downloadable title.

The company showcased the game again at Taipei Game Show, and announced that this is a much improved version. According to the announcement, a focus testing group of over 100 people was used to gather feedback, producing a much better version of the game with added voices and effects.

The game will support four players online, and so far four playable characters have been announced, even if more are expected. The title will be monetized by selling the ability to continue after being defeated, pretty much reproducing the old-style arcade experience.

The game was initially slated for release this spring, but a delay has been announced, and it will now come to the Asian and Japanese market this summer. While there's no announcement so far of a western release, due to its free to play downloadable nature, we'll just have to use a Japanese or Asian PSN account to play it.

A new Twitter account in Japanese has also been opened to create a channel of communication with the fals.
