Call of Duty: Modern Warfare 4 launches October 23 on PC, PlayStation 5, Xbox Series X/S, and Nintendo Switch 2, featuring a revamped DMZ extraction mode set in the radioactive Hajin region.
DMZ returns to the radioactive Hajin region
The updated DMZ mode places players in Hajin, a border region between Russia, North Korea, and South Korea. PCGuru reports the area is largely uninhabitable following a nuclear reactor meltdown, characterized by radiation and hazardous radioactive winds. Players must locate chemical, biological, and nuclear weapons left in underground military facilities while North Korea attempts to reclaim them.
The mode retains the extraction shooter loop: players deploy into an open area, collect resources, complete contracts or story objectives, and attempt to extract with loot. Activision claims this version is deeper and more cohesive than the beta version seen in Modern Warfare 2, incorporating direct player feedback.
Environmental factors now impact gameplay. Heavy rain reduces visibility, and dense fog alters how players approach buildings or evade opposing teams. Infinity Ward is also introducing a new squad-generation system for AI enemies, who operate in convoys, use helicopters, and station in guarded zones to create more unpredictable pressure.
Did you know? The campaign for Modern Warfare 4 becomes available to pre-order customers on October 16, one week before the full official launch.
Server Culling targets wallhack cheats
Infinity Ward is implementing “Server Culling” to stop cheaters from seeing players through walls. Server Culling adds layers to environmental elements to prevent the server from sending this unnecessary information to the client.
This system will be active at launch across all multiplayer maps, DMZ, Combat Outpost, and Warzone on all platforms. It operates alongside the existing Ricochet Anti-Cheat system.
PC requirements span from GTX 970 to RTX 5070 Ti
Activision has released a tiered set of PC specifications to support various hardware levels. Esport1 notes that the minimum requirements are low enough to run on most functioning modern PCs, while the Ray Tracing tier targets high-end enthusiasts.
| Specification | Minimum | Recommended | Ray Tracing |
|---|---|---|---|
| OS | Windows 10 | Windows 11 | Windows 11 |
| CPU | Ryzen 5 1400 / i5-6600 | Ryzen 5 3600 / i7-8700K | Ryzen 7 3700X / i7-10700K |
| RAM | 8 GB | 16 GB | 32 GB |
| GPU | GTX 970 / RX 470 / Arc A580 | RTX 3060 Ti / RX 6600 XT / Arc B580 | RTX 5070 Ti / RX 9070 XT |
All tiers require an SSD with 115 GB of available space. Gamekapocs and PlayDome report that PC players get exclusive features, including 4K resolution, HDR10+, and support for Nvidia DLSS 4.5, AMD FSR RedStone, and Intel XeSS 3. The game also introduces sub-frame mouse polling, a feature carried over from Black Ops 7, to decouple mouse input from the framerate.
Pro Tip: PC users must ensure TPM 2.0 and Secure Boot are enabled in the BIOS. Intel Arc users specifically need to enable Resizable BAR for the game to function.
Modern Warfare 4 Technical Updates
PlayDome reports that Modern Warfare 4 removes the requirement to restart the game after an update. The developers have also improved shader pre-loading and added an in-game benchmark tool. The PC version also includes an “Advanced Shader Delivery” system and enhanced FOV options.
