At Ultimate Guitar, the staff rated the album 9 out of 10 and stated: "Overall, Scale the Summit has done quite well to weather the changes of the past year, and while certainly there will be opinions one way or another on the line-up changes, the main thing we can take from In a World of Fear is that as far as the band's music goes, they're still more than capable of putting out some of the best quality instrumental progressive metal out there. For me, the key to this band's success has always been that they've stuck to playing to their strengths, and experimented only where they needed to. Perhaps an odd thing for a prog-metal band to do, but comparing this record to their first two, Monument and Carving Desert Canyons, there does seem to be a lot of fat trimmed from the music, yet seemingly something added. The variety of sounds on this record is something the band hasn't played with on this level yet, and this is definitely a good thing. It really does seem as every subsequent Scale the Summit record is always "their best", and this one is no exception. So far, this is their best record. The fact that this is their first self-released record, independent of a record label, only heightens this, and I'm certain we can expect more exciting things from the band in the future."[15]
