MW4 Open Beta Kicks Off With Korea-Set Multiplayer Maps & Movement Overhaul

Infinity Ward teases fresh gunplay and South/North Korea locales in first beta weekend

Snap says:

Private Park hits the beta streets like the fresh grunt the story demands—new movement, old grudges, and Korea on fire. Infinity Ward finally remembered how to make a map feel like a place instead of a killbox.

MW4's first open beta weekend is live, and Infinity Ward's Korea-set maps plus the movement overhaul are front and center. Silkworm, Lithium, and the dynamic Kill Block drop players into South Korean city streets and coastal spots with photogrammetry-scanned landmarks, PC bang billboards, and moving crab shack claws for that grounded but fresh vibe. The devs stripped out some cover to cut cognitive load and added pipe climbs, mantle slides over cars with gun up, and supine slides under garage doors so you actually feel like an action hero instead of a slow slog.

Slide over cars with your gun up and hear players yell 'Oh no way!'

Buddy if your monitor can't keep up that's between you and your ophthalmologist. Beta's 120 locked on Series X already.

The Korea maps have shown 14% higher engagement on preliminary telemetry. Pre-order bundles are converting 31% above prior title launch benchmarks at identical price points.
