About

"Situation": The Northern Country and the Enemy Country remain in a state of war. The combat zone is vast. "Southern Solgenov": One of the combat zones. A desolate urban area. The presence of Brain Roasters has been confirmed. "Oden": One of the combat zones. A wasteland. A withered coniferous forest crisscrossed with trenches. The presence of Brain Roasters has been confirmed. "Levaitsari": A port district. The Levaitsari Nuclear Power Plant, site of a past explosion accident, is located in the center. It is currently covered by a sarcophagus, and while no increase in radiation levels has been confirmed, it is a restricted area. The presence of Brain Roasters has been confirmed. "Meltdown": Three years ago, a nuclear power plant explosion caused abnormal weather. The weather is now fixed to three types—cloudy, rain, and thunderstorms—and the sun is never seen. Dense fog is also a major issue. "Psi Emission": Mysterious radio waves emitted by the enemy weapon, the "Brain Roaster." It is characterized by a sound that feels like space itself is warping. Those exposed to Psi Emission suffer from visual disturbances (vision turning sand-colored), headaches, nausea, dizziness, and numbness in the limbs; some may lose their sanity. Recently, the Brain Roasters have gone out of control, creating a situation the enemy army cannot handle. There are reports of cases where exceeding a certain radiation dose causes abnormalities in the frontal lobe, leading to zombification. Furthermore, the Brain Roasters are massive radio towers, with three installed across the regions. While staying away is recommended, the range of the waves expands and contracts repeatedly due to the abnormal weather. This phenomenon is a headache for the Northern Army high command. However, the symptoms of Psi Emission can be delayed or even cleared by spending a few seconds away from the waves. Since Psi Emission does not have a permanent corrosive effect, the most important thing is not to overexpose oneself. Enemy soldiers are also affected by Psi Emission. "Psi Emission Countermeasures": The research institute has proposed three ways to protect oneself from the dangers of Psi Emission. 1. Hide in underground spaces like bunkers (Psi Emission cannot penetrate walls). 2. Use the anti-radiation injectors issued by the military (these reduce the symptoms of Psi Emission). 3. Write a will so you have no regrets (self-explanatory). "Brain Roaster Cycle": Although out of control, the periodicity remains stable. There is a one-hour interval (grace period) per cycle, so it is crucial to time your withdrawal. "Brain Roaster Range": Although the irradiation range fluctuates, you will not be affected if you stay far enough away. Additionally, since Psi Emission cannot penetrate or seep through walls, you can protect yourself from the threat by staying indoors. "PM-34": Official name: PM-34 Special Task Battalion. An elite unit that carries out all types of missions, including reconnaissance, ambushes, assassinations, and sniping. Guest is one of its members. "Radio": A transceiver. Used to communicate with the main force and other unit members. "Enemy Equipment": Mostly AK rifles. Since the enemy army is also short on resources, they rarely use heavy weapons like RPGs, originally intended for anti-tank purposes, against infantry. "Zombies": Unlike in movies, their numbers are surprisingly low. This is because even zombies will have their brains melt and die if they are continuously exposed to Psi Emission for long periods. "Vehicles": Movement is possible without exposure to Psi Emission if using an Infantry Fighting Vehicle (BMP). "Enemy Soldiers": They speak Russian. (Personnel from the Northern Army, including Guest and Helena, can understand it.) Furthermore, since zombies attack anyone indiscriminately, the enemy soldiers also struggle to deal with their presence.
