Modern Warfare 4 Takes Aim at Smoother Multiplayer Ahead of Open Beta, Nintendo Switch 2 Launch

Call of Duty: Modern Warfare 4 is gearing up for this weekend’s open beta following a strong early access period that drew hundreds of thousands of players. The multiplayer shooter is expanding platform reach for the first time to Nintendo Switch 2, and Infinity Ward’s development teams are finalizing refinements based on early player feedback.

What the Team Is Building

Infinity Ward’s core philosophy for Modern Warfare 4 multiplayer centers on creating what Multiplayer Tech Designer Jack Hoppus calls “the most grounded, fluid experience.” The team targeted reducing friction in pain points while strengthening mechanics players already enjoy.

Movement received particular attention. The mantle system was completely rewritten to keep players in the fight—you can now ADS while mantling, cancel out of mantles when you spot danger, and perform mantle slides and supine slides. This design philosophy extends across Killstreaks, weapons, maps, and field upgrades.

Level design emphasizes clarity and playability over aesthetic complexity. The team reduced overall cover positions to lower the mental load of checking angles, created clearer lanes, and adjusted lighting to improve visibility without sacrificing art direction. The goal is maps that are both beautiful and fun to actually play on.

Kill Block, a dynamically changing map with over 500 different configurations, has seen positive player reception. The team plans to continue supporting it through launch and post-launch with additional slabs and new modes. Players are already testing it across Team Deathmatch, Hardpoint, Search and Destroy, Domination, and other modes.

Listening and Iterating

Early access feedback hasn’t centered on one unified complaint. Instead, the team is addressing numerous smaller adjustments: weapon balancing, movement feel, spawn logic, and time-to-kill tuning. Hoppus noted the team puts out milestone updates addressing these points and plays alongside the community to identify shared pain points. Recent updates have targeted weapon balancing, longer time-to-kill adjustments, and spawn logic refinement for certain modes.

Why It Matters

Call of Duty’s multiplayer has historically been defined by fast-paced gunplay and tight map design, though past entries sometimes struggled with overly complex level geometry and movement animations that pulled players out of combat. Modern Warfare 4’s focus on reducing friction speaks to lessons learned from those earlier experiences. By rewiring core mechanics like mantling and streamlining visual clarity on maps, Infinity Ward is attempting to make the skill gap clearer and gameplay more responsive—qualities competitive and casual audiences alike respond to.

The Nintendo Switch 2 port represents a significant platform commitment for the franchise. Getting Modern Warfare 4 running smoothly across console architectures with this level of multiplayer complexity is a technical undertaking that signals Activision’s confidence in both the title and the Switch 2’s install base.

The open beta this weekend will test whether these refinements resonate with a broader audience beyond the early access players. Watch for how the community responds to spawn adjustments and time-to-kill changes, and whether the development teams’ iterative pace continues into the official launch window.
