Entertaining but unpolished alternate history turn based strategy game focused around WWII but with vampires, werewolves, zombies, witches, Frankenstein, Van Helsing, Jack the Ripper, alchemists, and the occult. Starts off simple until you start unlocking more powers, characters, and equipment that you can pick up and the battles start becoming more dangerous when death can permanently lose you characters and proper management of abilities and explosives to destroy tanks become necessary. Has a variety of overwatch and movement style commands as well different abilities and weapons and items that can be equipped to characters. It's a very unusual turn based game with large maps where a mistake can easily lead to a character getting killed, an odd camera, and some strange mechanics but I did enjoy my time with it back around the time of release.

This game might as well be the definition of underrated. On release, IGN gave this a 2.5/10, and various other critics awarded it oddly low scores. Is Operation Darkness excellent? Not at all, but it has a lot of great ideas and a fair amount of decent stages. Music and voice acting are also pretty good. I honestly think a lot of the negativity stems from the demo stage being one of the worst looking and least interesting in the entire game. This is a game worth checking out - wouldn't necessarily call it a gem but it's like a cool rock or something.
