After the Phantom Demon Siege, humanity will not only face hordes of demons, but will also attempt to rebuild devastated areas and reclaim lost territories. To this end, the "Order of the Hunters" has formed special rapid response teams known as Shadow Squads. These teams are tasked with carrying out high-risk missions to ensure humanity's survival and slow the demonic expansion.

You and your commando are part of these forces. Each mission takes you to locations infested with supernatural creatures, where you must complete crucial objectives such as recovering artifacts, rescuing survivors, destroying demonic structures, and securing critical areas.

As you complete these tasks, you discover that more sinister forces are manipulating events in order to keep the portals open. Now, each mission is not only about survival, but also about finding clues that can unravel a conspiracy that threatens humanity's fragile resistance.
