Modern Warfare 4 Open Beta Day 4 Patch: Weapons, End Time, Rewards

The Modern Warfare 4 Open Beta has ended. Servers closed September 1 at 10 a.m. PT / 1 p.m. ET after a free Weekend Two on PlayStation 5, Xbox Series X|S, Xbox on PC, Steam, Battle.net, and Nintendo Switch 2. A preorder or beta code cannot restore access now.

Both test weekends are over, and the separate beta client no longer grants access. Players who earned cosmetic rewards should keep the same Activision account linked for the October 23 launch. The Early Access versus Open Beta schedule preserves how the two completed windows differed.

What changed in the MW4 Beta on August 31?

August 31 was the final full day of the Open Beta. Double XP and Double Weapon XP were active, Transit 213 24/7 and 6v6 Gunfight on Kill Block were in the playlist set, and the servers closed September 1 at 10 a.m. PT / 1 p.m. ET. Infinity Ward also released a sizable weapon-tuning pass and another group of Zodiac Resurgence fixes.

• Main weapon buffs: Krait P68 mid-range damage rose from 33 to 34 and its second range now reaches 39.1 meters. PPSh-41 ranges increased slightly. ISO Nightshade max damage rose from 20 to 21, several ranges increased, and its head multiplier moved from 1.25 to 1.3. Han 86 max and minimum damage increased from 22 to 23 and 18 to 19, while the Hyeon Burst neck multiplier increased from 1 to 1.1.
• Main weapon nerfs: FiNN LMG max damage fell from 33 to 30 and its middle range became shorter. Type 73 lost max and middle damage and some range, although its neck and upper-torso multipliers increased. Oris 8.6 lost range, the M4 Hurricane attachment dropped from 30 to 27 max damage and from 1.3 to 1.25 head damage, and both long-range Rezi 12 barrel bonuses were reduced.
• Other tuning: The Axion in default loadouts gained a middle damage tier while its maximum-damage range became shorter. Infinity Ward says average time to kill is now closer to its target after Weekend One, so this is individual weapon balancing rather than a new global TTK change.
• Zodiac Resurgence: The update adjusts global color balance, reduces bloom between interiors and exteriors, and makes close-range character outlines brighter. Enemy ascenders and parachute landings should be easier to hear, supply-box audio travels about 50% less distance, squadmate nameplates now appear while aiming at them, and a duplicate squad indicator bug was fixed.

During the final session, the practical order was to use the XP bonuses, reach any remaining reward level, and then test the newly tuned weapons or Zodiac visibility changes. Playlist availability continued to rotate before the servers closed.

What changed in the MW4 Beta on August 30?

Infinity Ward activated Double XP and Double Weapon XP at 10 a.m. PT on August 30 to help players reach Level 30, unlock the Beta Forged blueprint, and level weapons before the beta ended. The patch notes did not give those bonuses a separate end time.

• Final playlist additions: Transit 213 received a dedicated 24/7 playlist, and 6v6 Gunfight on Kill Block joined the menu. Quick Play included Team Deathmatch, Domination, Hardpoint, Kill Confirmed, Search & Destroy, Inflation, and Hijack. Zodiac Resurgence Quads and Casual Quads rotated by time of day.
• Transit 213 score limits: Team Deathmatch increased from 100 to 150, while Kill Confirmed increased from 75 to 100.
• Multiplayer fixes: Operator models should enter the selection screen at their intended quality on lower-end hardware, and Combat Outpost received a fix for poor streaming quality at the start of a match.
• Warzone changes: Ground-loot pickup interactions are more precise, armor-hit feedback is clearer, HUD shake is disabled for the rest of the beta, screen and gun shake were reduced, and several downed-state, loot-feed, and menu-loop bugs were fixed.

Infinity Ward said playlist availability could flip during the day. The final live menu, rather than every item in the patch notes, determined what remained selectable before shutdown.

When did the MW4 Open Beta end in each time zone?

The servers closed at the same moment worldwide on Tuesday, September 1: 10 a.m. Pacific, noon Central, 1 p.m. Eastern, 5 p.m. UTC, 6 p.m. in the United Kingdom, and 7 p.m. in Central Europe.

The cutoff applied to the live service rather than an individual account. A downloaded client, unfinished match, preorder, or previously redeemed code did not extend the session.

Can you still download and play the MW4 Open Beta?

No. A store listing or installed beta client may remain visible, but the published test window ended September 1 and the client no longer provides live beta access.

1. Do not buy a code or account. Codes were only for the August 21–25 Early Access period and cannot reopen the ended beta.
2. Treat any remaining beta download as an inactive test client, not proof of a new or extended session.
3. Keep the Activision account that earned your rewards linked to the platform account you plan to use at launch.
4. Use Activision’s official game and support pages for October 23 launch information or any future test announcement.

If a storefront still shows Play Now or an old beta tile, that does not override the official end time. Avoid unofficial installers, shared accounts, and sites selling expired access.

What was playable in Weekend Two?

The Open Beta included Entrenched, a playable campaign mission set during the conflict on the Korean Peninsula. It was a single preview mission, not early access to the full campaign.

Multiplayer expanded for Weekend Two with the Lithium 6v6 map and the Hijack mode. Kill Block remained the beta’s modular combat space, while Ground War: Combat Outpost added larger battles and two Ground War maps.

Warzone was playable in a Call of Duty beta for the first time. The test used Resurgence on Zodiac, a new map built around twelve themed points of interest. Playlists rotated during the event, so not every listed mode was available at every hour.

The list above records the stable content set, not a promise that every playlist stayed selectable all weekend. Activision reviewed match data and player feedback daily and changed rotations and balance during the live test.

All eight MW4 beta rewards and their levels

Weekend Two raised the cap to Player Level 30. Returning players continued from their Early Access level, while new players began at Level 1. The beta is over, so these eight rewards are no longer earnable:

• Level 4 — “Through the Paces” Legendary Emblem
• Level 8 — “First Served” Weapon Charm
• Level 12 — “Meonjeo” Legendary Weapon Sticker
• Level 16 — “Last Charge” Legendary Calling Card
• Level 20 — “Dread Tiger” Operator Skin for Reece
• Level 23 — “Field Tested” Epic Spray
• Level 26 — “Beta Rights” Epic Loading Screen
• Level 30 — “Beta Forged” Epic Han 86 Weapon Blueprint

Activision says the rewards cannot be earned after the beta ends. Cosmetics unlocked before the cutoff remain tied to the Activision account that earned them and become available with Modern Warfare 4 on October 23.

Does MW4 beta progress carry over?

Cosmetic beta rewards carry over; gameplay progress does not. Player level, weapon unlocks, and other test progression reset when the beta closed. The eight level rewards and other eligible beta cosmetics remain on the Activision account that earned them for the full game.

Cross-progression during the beta used the linked Activision account across supported platforms. To receive earned cosmetics at launch, keep using the same linked profile rather than creating a second account.

Do you need a preorder or beta code?

No current code can reopen the beta. Preorders and beta codes applied only to the August 21–25 Early Access window; the August 28–September 1 Open Beta needed neither. The MW4 beta code status and redeem guide explains the closed redemption flow and common account messages.

The completed test required an internet connection and an Activision account, and console online-multiplayer subscriptions could apply. Those requirements do not imply that beta servers remain available.

What is different on Nintendo Switch 2?

This was the first Call of Duty Open Beta on Nintendo Switch 2. It supported cross-play and cross-progression, Joy-Con 2 mouse controls, gyro controls, the Nintendo Switch 2 Pro Controller, HDR, and handheld play.

Activision let Switch 2 beta players try selected Vault Edition content, including operator packs and five Signature Weapon Blueprints. That temporary access ended with the test and did not create a free full-game entitlement.

PC security requirements and final beta changes

TPM 2.0 and Secure Boot must be enabled to play online modes on PC. These are security checks used by the game’s anti-cheat protections, not optional graphics settings.

Weekend Two arrived with broad weapon tuning, spawn adjustments, audio changes, attachment fixes, and playlist updates. The final beta patch notes remain the primary record when advice from Weekend One conflicts with later test values.

What was worth prioritizing before the cutoff?

1. Reach Level 4 for Create a Class. That replaced the default-loadout limitation and opened proper weapon and attachment testing.
2. Use Daily Challenges. Stacking objectives reduced the time needed to move through the temporary level track.
3. Aim for Levels 20, 23, 26, and 30. Those milestones contained the operator skin and the three Weekend Two rewards.
4. Try each major branch. Entrenched, standard Multiplayer, Ground War, and Zodiac Resurgence tested different parts of the full game.

What happens after the MW4 Open Beta?

The Open Beta closed September 1 at 10 a.m. PT. Modern Warfare 4 now moves toward its October 23 launch on PS5, Xbox Series X|S, PC, and Nintendo Switch 2. Digital preorders include campaign access beginning October 16, but beta gameplay progress reset after the test.

The practical next step is to keep the Activision account that earned any cosmetics linked, remove the inactive beta client if storage is needed, and use official launch information rather than expired beta codes or unofficial downloads.
