You won't be forced to play through a series of levels back-to-back, as the streets of the town-hub are free to explore before you take on any unlocked mission or replay completed ones. Besides guns and explosives you will rely on the occult powers of The Veil, a distorted reality in which you can slow down time, block bullets and discover secret passages.

Darkest of Days

Darkest of Days is an FPS from 8Monkey Studios, published by Phantom EFX. The game is seperated from the average FPS game by using mainly the Civil War and World War 1 and its settings, two time periods not often depicted in action video games. Sometimes you will use period weapons which are slow and cumbersome, and then you will be granted a modern day weapon with which to cause havoc, which always feels very satisfying.
