Omega Force is best known for the Dynasty Warriors series and its related hack n' slash spin-offs, due mostly to the fact that it's made a billion of them. In fact, the last truly unique game Omega Force made was the rather good Bladestorm back in 2007. 

Trinity: Souls of Zill O'll is the first deviation from the studio's formula in almost four years. Unfortunately, a change of pace is not always for the better.
