Infinity Ward closed the Modern Warfare 4 Open Beta on September 1 with a rare thing in the Call of Duty world: a public, itemized list of what it still isn't happy with — and what it's actively changing before MW4 launches on October 23, 2026. If you played either beta weekend and walked away unsure about the game, this is the post that tells you exactly which of your complaints the devs heard and are acting on.
This is a confirmed-vs-rumored breakdown built straight from Infinity Ward's own beta wrap-up on callofduty.com, cross-checked against the Weekend 2 patch notes and launch coverage. No leaks stated as fact. Here's every change area on the table, why it matters, and what it means if you're deciding whether to pre-order.
Quick answer (TLDR): Coming out of the MW4 Beta, Infinity Ward publicly confirmed it is still working on five multiplayer areas — TTK and weapon tuning, Perk tiers, aim assist, spawn logic, and Nintendo Switch 2 performance — plus four Warzone areas (UI/HUD readability, audio/footsteps, movement, and map pacing). The studio said plainly it is "not fully satisfied with TTK" and will "continue dialing in our weapons ahead of launch." None of this is a leak — it's from the official beta patch notes dated September 1, 2026. The full game arrives October 23, 2026; the beta ended September 1 and its progression does not carry over.

What did Infinity Ward actually say after the MW4 Beta?
The source everyone is quoting this week is Infinity Ward's own beta wrap-up, published in the official MW4 Beta patch notes on September 1, 2026 (support.activision.com). Rather than the usual "thanks for playing," the studio listed specific systems it's still tuning.
The framing matters. Infinity Ward wrote that its "north star for this Beta was consistent updates and communication throughout," and that between Weekend 1 and Weekend 2 it "made extensive changes to weapons, TTK, movement, spawns, and more." Then it did the unusual part — it named the areas it still wants to improve heading into launch.
For a pre-order decision, that's the useful signal: the biggest beta complaints (gunfights feeling off, spawns, aim assist) are officially acknowledged, not brushed off. Below is each area, ranked by how much it changes the moment-to-moment game.
MW4 launch changes, ranked by impact
Here's the confirmed multiplayer focus list from the beta wrap-up, ordered by how directly each one affects how the game feels when you play:
| # | Change area | Infinity Ward status (confirmed) | Why it matters |
|---|---|---|---|
| 1 | TTK & weapon tuning | "Not fully satisfied… will continue dialing in our weapons ahead of launch" | Sets the entire pace of gunfights |
| 2 | Spawn improvements | "Made big changes in Weekend 2 but still see places to improve" | Spawn deaths were a top-3 beta complaint |
| 3 | Aim assist | "Further aim assist changes… already working on some updates" | Controller vs MnK balance, feel of tracking |
| 4 | Perk tiers | "Adjusting Perk tiers to create more meaningful choices" | Loadout depth and build variety |
| 5 | Switch 2 performance | "Nintendo Switch 2 performance improvements" | Frame rate / stability on the new platform |
1. TTK and weapon tuning — the headline problem
Time-to-kill (TTK) was the divisive topic across both weekends. Weekend 1 shipped with a fast TTK that many longtime players loved; the Weekend 2 update slowed it down to address spawn and pacing feedback — and a loud chunk of the community felt that made gunplay worse, not better.
Infinity Ward's own words: "While the changes throughout Beta were an improvement, we aren't fully satisfied with TTK and will continue dialing in our weapons ahead of launch." Independent coverage backed up the tension — Forbes' Erik Kain wrote on September 8 that Weekend 2 "doesn't feel nearly as good as the first weekend," and hardcoregamer's beta preview noted the slower TTK left "Snipers, Marksman Rifles and shotguns completely overpowered."
What it means: expect launch weapon values to sit somewhere between the two beta weekends, with more per-weapon balancing so each class does its job. If you want to hit the ground running on day one, weapon leveling and camo grinds are unaffected by TTK tuning — the guns still level the same way, so a head-start plan still pays off. (See our fastest weapon leveling guide and the beta TTK/weapon nerf breakdown for the numbers.)
2. Spawn improvements — the quiet killer
Spawns don't trend on social the way TTK does, but they quietly ruin more matches. Infinity Ward confirmed it "made big changes in Weekend 2 but still see places to improve, especially on certain map/mode combinations."
That "map/mode combinations" phrasing is the tell: the studio isn't doing a blanket spawn rewrite — it's targeting the specific maps and modes where spawn-trading and behind-you deaths spiked. Combine that with the 12 confirmed launch maps and you get a clearer picture of where the launch experience will differ from beta.
3. Aim assist — controller feel is still being tuned
Aim assist is the eternal Call of Duty flashpoint. Infinity Ward flagged it directly: "We previously said that aim assist changes during Beta were not exactly where we wanted to land, and we're already working on some updates."
Translation: the beta's aim assist strength and rotational behavior are not final. If you play on controller, don't build muscle memory around exactly how tracking felt in Weekend 2 — it will move. Our aim assist explainer covers how the system works and what "rotational" vs "slowdown" aim assist actually do.
4. Perk tiers — more meaningful loadout choices
Infinity Ward committed to "adjusting Perk tiers to create more meaningful choices." In the beta, several perk picks felt mandatory rather than optional, which flattens build variety. Retiering perks is a lower-visibility change than TTK, but it's the one that most affects long-term loadout creativity once the meta settles. See the full beta perks list for the starting point they're tuning from.
5. Nintendo Switch 2 performance
MW4 is the first mainline Call of Duty to ship on Nintendo Switch 2, and Infinity Ward explicitly listed "Nintendo Switch 2 performance improvements" as a launch focus. If you're planning to play on Switch 2, this is the one to watch — beta performance was a talking point, and the studio is targeting it before October 23.
What is Infinity Ward changing in Warzone for launch?
The beta also included a Warzone Resurgence taste on the new Zodiac map, and Infinity Ward gave Warzone its own focus list — all confirmed, all from the same September 1 wrap-up:
- UI and HUD readability — "clear opportunities to improve UI and HUD readability."
- Audio, especially footsteps — "a major focus, and we've already begun making adjustments based on player feedback."
- Movement — reviewing feedback "with an emphasis on delivering the fluid, responsive feel players expect from Warzone while keeping movement grounded."
- Map pacing — "evaluating overall map pacing to ensure it's in the best possible place for launch."
Infinity Ward called this "an early look at some of our priorities coming out of Beta" and said Warzone updates will "follow" the MW4 launch. So expect the multiplayer changes first, then a Warzone-specific pass.

Confirmed vs rumored: don't get these mixed up
This is where a lot of the internet gets sloppy. Here's the clean split:
Confirmed (Infinity Ward / Activision official):
| - MW4 releases October 23, 2026 on PS5, Xbox Series X | S, PC, and Nintendo Switch 2 (callofduty.com; Xbox store). |
|---|
- The five multiplayer focus areas and four Warzone focus areas listed above (official beta patch notes, Sept 1).
- The beta ended September 1; beta progression does not carry over to the full game — unlocked beta rewards become available at launch, but your levels reset (Open Beta FAQ). Full breakdown in our beta progress carry-over guide.
Rumored / not confirmed (do not treat as fact):
- Exact final TTK values at launch. Infinity Ward said it's still tuning; no final numbers are published.
- Specific per-weapon damage at launch. The beta patch notes are beta values, not launch values.
- Any "leaked" perk list or aim-assist numbers for the full game.
If a video or post gives you exact launch TTK numbers today, it's a prediction, not a confirmation. The studio explicitly said it will "share more details on the process and our work in the weeks ahead."
What this means if you're deciding whether to pre-order
The honest read: the beta had real problems, and Infinity Ward publicly owned the biggest ones instead of pretending they didn't exist. That's a better signal than silence. If the Weekend 1 gunfeel is what sold you, the "not fully satisfied with TTK" line is encouraging — they're not locked into the slower Weekend 2 pace.
If you do plan to jump in at launch, the smartest prep isn't guessing at the meta — it's removing the two things that actually eat your time on day one:
- Sweaty, high-skill lobbies from launch-week matchmaking. Skill-based matchmaking hits hardest in the first weeks when the population is a mix of pros and casuals. (See how SBMM works at MW4 launch.)
- The grind to unlock guns and camos before the meta even settles.
Whatever Infinity Ward lands on for TTK and perks, the leveling systems underneath don't change — so a head-start on weapons, camos, and easier lobbies pays off regardless of the final tuning.

FAQ
What is Infinity Ward changing in Modern Warfare 4 for launch? Coming out of the beta, Infinity Ward confirmed five multiplayer focus areas — TTK and weapon tuning, Perk tiers, aim assist, spawn improvements, and Nintendo Switch 2 performance — plus four Warzone areas: UI/HUD readability, audio (especially footsteps), movement, and map pacing. All of these come straight from the official beta patch notes dated September 1, 2026.
| Is Modern Warfare 4 out yet? No. MW4 launches on October 23, 2026 on PS5, Xbox Series X | S, PC, and Nintendo Switch 2. The Open Beta ran across two weekends and ended September 1, 2026 — the game itself is not playable yet outside of that beta. |
|---|
Did Infinity Ward fix the TTK? Not fully, by their own admission. The studio said, "While the changes throughout Beta were an improvement, we aren't fully satisfied with TTK and will continue dialing in our weapons ahead of launch." Expect launch TTK to keep changing between now and October 23; any exact launch numbers you see today are predictions, not confirmations.
Does my MW4 Beta progress carry over to the full game? No. Beta progression does not carry over — your levels reset for the full launch. Unlocked beta rewards (like the Beta Forged Blueprint) become available in the full game when it launches on October 23. See our beta-vs-full-game breakdown for the complete list of what you keep and what resets.
Are the beta weapon damage numbers the same as launch? No. The values in the beta patch notes are beta tuning, not final launch values. Infinity Ward explicitly said it's still balancing weapons ahead of launch, so treat beta damage stats as a snapshot, not the shipping numbers.
Is aim assist final in Modern Warfare 4? No. Infinity Ward said aim assist during the beta was "not exactly where we wanted to land" and that it's "already working on some updates." Controller players should expect aim assist behavior to change before launch.
