The Modern Warfare 4 beta spans two weekends: Weekend One lets players reach level 20 with initial rewards, while Weekend Two raises the cap to level 30 and unlocks additional weapons, equipment, perks, field upgrades, killstreaks, and rewards.

The article previews the Modern Warfare 4 beta and outlines what players can expect when they start the game.

Weekend One brings a playable campaign mission named Entrenched, the new Mobility Course, 21 multiplayer weapons (14 available at start and 3 additional via specific loadouts or Entrenched), plus progression that unlocks weapons, equipment, Perks, Field Upgrades, Killstreaks, and more; Create a Class unlocks at Level 4.

Infinity Ward leadership and Call of Duty social channels are being unified in messaging to present a coordinated stance on updates and feedback integration.

Historical context is used to explain why developers stay vigilant against repeat exploits while preparing for live feedback.

Multiplayer design lead Jacky Reynolds says the team plays the game extensively to identify and block powerful, exploitable strategies, citing past issues like One Man Army from MW2.

Reynolds notes developers test the game themselves to prevent exploits from undermining the sandbox, with tighter internal playtesting as players have improved.

The team emphasizes ongoing balance work driven by player feedback after the beta, rather than nerfing arbitrarily, and plans continued updates through launch and live support.

Infinity Ward highlights collaboration with pros, creators, and CDL players to shorten feedback loops and align the game with competitive and casual expectations.

The team aims to tune weapons and systems for balance, avoiding over-nerfs, with decisions shaped by post-beta player feedback.

Open communication and ongoing balance discussions will continue beyond the first weekend, guiding adjustments after the beta and into launch.
