GameSpy N-Gage 
Review, by Thomas Flint: "While Requiem of Hell isn't Diablo or Baldur's Gate, it is the only title of this type on N-Gage right now. So, if you're desperate for an action RPG this is it until something better appears on the horizon." [Score: 2 out of 5]

IGN N-Gage 
Preview, by Adam Tierney: "Aside from a trailer with plenty of death metal, there wasn't anything really original about this game in the presentation, and it's definitely on the light side for features when compared to the rest of the N-Gage's upcoming library."
