Look, let's be honest—Call of Duty: Modern Warfare 4 has just dropped a brand new trailer titled 'Sacrifice', cranked up to maximum immersion with actual North Korean music.

The official Call of Duty account dropped the 30-second teaser via its official YouTube channel on the 2nd. The trailer depicts the North Korean military, positioned as the primary hostile faction, complete with the haunting tune 'Where Are You, Dear General'—one of the top five North Korean revolutionary operas, which happens to be surprisingly well-known even in the West.

The video kicks off by cross-cutting propaganda poster-style artwork and terminology with scenes reflecting actual North Korean society. It then deepens the world-building by mixing in peeks at the North Korean elite lifestyle alongside edited footage from the story trailer released back in September. To top it all off, a faint, chilling children's countdown echoes near the end of the clip, ratcheting the eerie vibe right up.

Meanwhile, another briefing dropped on the 3rd, breaking down a brand new system designed to combat wallhacks. Alongside the upcoming Modern Warfare 4 update, the legacy server data processing method is getting a rework, meaning data regarding enemies behind walls won't even be sent to the server in the first place, effectively neutralising wallhack detection exploits. The developer hopes this will drastically cut down the frequency of wallhack usage, leaving players with a much cleaner playing field moving forward.
