Modern Warfare 4 Beta Weekend 2 Update Will Rework Movement, Spawns, and Gunfights

Call of Duty: Modern Warfare 4 Weekend 2 will begin at 10 AM PT on August 28, bringing a large beta update focused on time-to-kill, spawns, movement, aim assist, and Killstreaks. The patch will also add new Multiplayer content, the Zodiac Resurgence map, and a higher level cap.

Infinity Ward has made changes across every weapon in the beta as part of an effort to give players more survivability without making guns feel too weak at range. Tactical Sprint will no longer be enabled by default, while Hardpoint will receive a new spawn prototype and temporary spawn protection will gain Battle Hardened.

The update will be available when the Open Beta begins at 10 AM PT on August 28. The Open Beta is scheduled to run through 10 AM PT on September 1. Players can find the complete official August 28 patch notes below.

Modern Warfare 4 Beta Weekend 2 changes

Movement is getting one of the most visible changes. Tactical Sprint will move to the Blood Rush Perk, its sprint-to-fire time will match base sprint, and its speed will be reduced by 4%. Sliding will also be slower and cover less distance, while knife and pistol sprint speeds will increase.

Spawn behavior is being tuned across respawn modes, with fewer spawns near squad members and a partially improved Hardpoint system. Hardpoint on Rooftops will remain disabled because of a spawn bug. Battle Hardened will also reduce the effects of flash and concussion grenades immediately after a player respawns.

Killstreaks will cost 1 additional kill across the board. The UAV will have 60% less health and fly 12% lower, while the Artillery Beacon will fire fewer missiles and cover smaller damage and knockdown areas. The changes are meant to keep matches centered on gunplay instead of repeated streak activations.

Aim assist will receive global adjustments that also apply to Warzone. Infinity Ward said the tuning is not final and will continue to be adjusted before launch.

New beta content and PC changes

Weekend 2 will add the Lithium 6v6 map, the Hijack mode, Ground War: Combat Outpost with 2 new Ground War maps, and Zodiac Resurgence Quads. Zodiac is set in South Korea at a weapons manufacturing facility, with points of interest including Old Mine, Solar, Trackline, and the sewers.

The beta level cap will increase to 30. The available playlists will include Quick Play, Open Moshpit, Mobility Course, 10v10 Gunfight on Kill Block, Hijack, and Zodiac Resurgence Quads. Team Deathmatch and Kill Confirmed will also receive higher score limits.

PC players will see performance and frame rate stability improvements, lower memory usage on High VRAM GPUs, and fixes for intermittent GPU hitching across GPU manufacturers. Online play still requires TPM 2.0 and Secure Boot to be enabled. Activision is gathering information from affected players through its TPM report form and directs players to its Secure Attestation Wizard.

Patch Notes for Call of Duty Modern Warfare 4 Beta

The August 28 notes cover the beta’s largest Weekend 2 adjustments, followed by detailed weapon values, audio changes, interface updates, bug fixes, and known issues.

TIME-TO-KILL

After some updates last week, we still weren’t where we wanted to be with time-to-kill. We’re aiming for a slight increase to TTK so instead of changing base health, we focused on weapon tuning to improve durability without making weapons feel too weak at range. Every single weapon in our Beta has received an update for Weekend 2. These changes create more survivability and room for skill expression in combat.There’s more work to do here and we’re looking forward to hearing your feedback.

WINDOWS SECURE ATTESTATION

As we’re heading towards Weekend 2 of the Call of Duty: Modern Warfare 4 Beta, here is a reminder of the security requirements that need to be met in order to play any online mode on PC:

• TPM 2.0 must be enabled;
• Secure Boot must be enabled.

We are aware that some PC players may encounter issues after going through the process. These issues may be due to firmware, hardware or OS problems which may prevent your PC from passing Microsoft Azure Attestation.

• We are actively working with Microsoft and motherboard manufacturers to improve the experience for affected players.

If you are unable to access the MW4 Beta, that does not mean you will be unable to play at launch.

• Over the weekend, we will be gathering information from players who are experiencing the issue through this form
• We will be working with hardware manufacturers on your behalf to get these issues fixed.

Ground War: Combat Outpost joins the Open Beta Saturday. The beta team will continue providing updates during each full day of the test.
