Geekpulp has reviewed Kingdom Under Fire: Circle of Doom for the Xbox 360.
"This review might come across as overly negative, but it's worth noting that Circle Of Doom is a passable game. I've compared it to Ninety Nine Nights, a game that I played through to the end in spite of horrid voice acting (L-l-landslide!?) and dubious skill requirements, and I definitely prefer Circle Of Doom"
