Modern Warfare 4's campaign took its score from 53 to 82. On Friday, everyone else arrives.

Call of Duty: Modern Warfare 4 opened its campaign on Friday, October 16, a week early, to everyone who pre-ordered it digitally. DMZ, the extraction mode, followed for the same players on Tuesday, October 20. On Friday, October 23, everything else arrives: multiplayer, and the full game for everyone, on PlayStation 5, Xbox Series X|S, PC through Steam, Battle.net and the Xbox app, Xbox Cloud Gaming, and Nintendo Switch 2. The standard edition is $69.99 and the Vault Edition $99.99, and it is not on Game Pass on day one.

The morning the campaign unlocked, our score for the game was 53, from 208 reactions. This morning it is 82 from 3,044, at very high confidence. Nearly all of those 29 points come from one thing: people finally had something to play.

We measure what people actually say about a game in public social media conversations and Steam reviews, classified and scored nightly with the sample size and confidence beside every number. Nobody clicks a star.

Before the campaign, there was little to react to

Modern Warfare 4 counts as playable from its multiplayer beta in late August, so it already had a score before the campaign opened. Very little of that score came from playing anything. Of the 199 reactions posted before October 16, 11% were positive, 6% were negative, and 83% were neutral or mixed: people passing along trailers, dates and news rather than saying what they thought. A score built mostly on neutral posts sits near the middle, and 53 is what that looks like.

Then the campaign landed

The first 127 Steam reviews arrived on October 16, and 80% of them were thumbs up. The next day brought 517 more, and 94% of those were. Scored on their own, the reactions posted on the campaign's first day come to 69 from 255, and the next three days to 82 from 647, 86 from 604 and 86 from 601. Together, the four days when the campaign was the only thing to play score 83 from 2,107 reactions.

What people are reacting to is the story. Story scores 92 from 1,847 mentions, the most discussed aspect by a distance, and the campaign itself is named 330 times, 96% of them positively. Reactions that talk about the campaign without bringing up multiplayer score 89 from 1,451. Infinity Ward is named 181 times at 69% positive, and Captain Price 67 times at 61%. Graphics score 85 from 370 mentions and gameplay 83 from 775. Among the 2,305 reactions from people who say they have played it, 78% are positive and 8% are negative.

The weak spots are just as clear. Performance scores 47 from 354 mentions and difficulty 46 from 172, the two lowest of the seven things we measure. The hardware people name shows where the performance trouble is: PC comes up 53 times at 17% positive, Switch 2 44 times at 18%, and ray tracing 37 times at 5%. Value sits at 52 from 361 mentions, and multiplayer, which nobody outside the August beta has played yet, at 61 from 418. Activision is named 68 times, 22% of them positively.

The people playing it are the happy ones

Split by where it was said, the gap is wide. The 2,081 Steam reviews in our sample score 89, with 85% positive and 7% negative, and every one of them comes from someone who owns the game. Social media scores 63 from 963 reactions, and the difference is not anger: only 5% of those reactions are negative. It is that 64% are neutral or mixed, much like the posts behind the early 53.

Valve's own count agrees with our Steam sample. At 3pm Eastern on October 21 the game was rated Very Positive on Steam, with 5,368 of its 5,851 reviews in every language thumbs up, 92%. In our sample, 1,922 of 2,081 are thumbs up, also 92%.

DMZ brought the biggest crowd, and the first cool days

DMZ early access opened on October 20 and drew the biggest audience of the week. Twitch peaked at 170,299 viewers that day, against 64,558 on the campaign's first day and 25,198 on the Monday before. So far on Wednesday the peak is 92,606.

It also brought the first cool days. The reactions posted on October 20 score 82 from 571, after 86 on each of the two days before, and the ones posted so far on Wednesday score 78 from 167. The Steam thumbs-up rate went from 95% on Sunday to 91% on Tuesday and 86% so far on Wednesday. DMZ itself is named 282 times, and exactly half of those mentions are positive. Performance, already the weak spot, slipped further: 39 from 77 mentions in reactions posted since Tuesday, against 48 from 259 in the four days before. The headline score barely moved, 83 on Tuesday morning and 82 today, because it counts every reaction since release and the campaign days still make up most of them.

What Friday could do

Gears of War: E-Day is the closest precedent in our data. Its Premium Edition early access opened on October 1, five days before its worldwide launch. The score settled inside those five days, at 65 by the fourth morning, and the launch did not move it. The reactions posted during early access score 65 from 4,017, launch week's score 66 from 6,036, and the published score has read 65 every morning since October 5, now from 12,866 reactions. When the people arriving on launch day play the same game as the early crowd, the score holds.

Modern Warfare 4's Friday is different, because the new crowd gets a different game. Early access has been the campaign, and since Tuesday DMZ. Friday adds multiplayer, the mode many players buy Call of Duty for, and it adds everyone on every platform, including the hardware people already complain about. The reactions we have that talk about multiplayer or DMZ without mentioning the campaign score 61, from 169. That is a small sample, but it points one way.

As an illustration, not a forecast: if launch week brings reactions that read like those multiplayer posts, half as many again as we have today would take the score to 79, as many again to 76, and twice as many to 72. A first week of steady servers and fewer performance complaints would keep it closer to where it is now. The campaign's 89 is not going anywhere. The question is how much of the conversation it still is by next week.

Price may matter too. Gears of War: E-Day launched into Game Pass, and its social media value score rose from 38 during early access to 55 in its first days after launch, as people who had not paid $70 or $100 arrived. Modern Warfare 4 is not on Game Pass on day one, so everyone arriving on Friday will have paid for it, and value already sits at 52. Steam also publishes player counts only from a game's official release, so Friday is the first day we will see how many people are playing there.

Where 82 sits

Of the 301 games we score, 95 score higher than Modern Warfare 4 and 9 others are level with it. Among this fall's big releases it sits with Control Resonant, 82 from 17,466 reactions, and Ace Combat 8: Wings of Theve, 80 from 12,607, well above Gears of War: E-Day at 65 from 12,866 and Wardogs, the multiplayer shooter that launched in September, at 57 from 20,785. The year's other annual series have not fared well: EA Sports FC 27 scores 38 from 3,340 and NBA 2K27 41 from 2,126.

Friday will show which game the score is really about. Today it is about a campaign people love, built on 3,044 reactions, two thirds of them Steam reviews. From Friday it will be about the whole thing, played by many more people on many more machines, and we will score it every night.
