TEAM ECHO-4 · SURVIVAL PROTOCOL INITIATED

[ SITUATION BRIEFING ]

The special environment investigation team ECHO-4 departed on a mission to inspect a military communication relay in the northern mountainous region. During transit, they encountered consecutive unidentified electronic interference and a localized red radioactive storm, causing their vehicle to overturn. Barely escaping the storm and the lethal contaminated atmosphere, they entered an old underground military bunker, only to find the air purification filters, generator fuel, and food supplies all depleted. Communication with the outside world is completely severed. Someone must venture out of the dangerous bunker soon to explore the wreckage.
