XSEED Games have released Valhalla Knights 3 on the EU PlayStation Store today, exclusively for PS Vita, costing £23.99. The series is known for its punishing difficulty and warped morality, but includes a wealth of content for "industrious players." The Japanese version also included some fairly raunchy stuff, though I don't know how much of it made it through to the UK.
Valhalla Knights 3 is famed for being properly tough - "b*stard hard" as our own Brendan Griffiths likes to say - but met with a mixed reception when it launched Stateside earlier this year. Definitely one to think long and hard about before investing in, though it's always nice to see European Vita owners getting more stuff to play.
