The fourth (technically seventh) game in the series, Call of Duty 4: Modern Warfare replaces World War II combat stuff with modern (well, modern back in 2007) combat stuff. The intense depiction of modern combat, coupled with a slick framerate and polished multiplayer, made the game a massive hit for future Call of Dutys to come.

Of course, this also meant it was more susceptible to being pried open for unused stuff.

To do:
  • Upload more unused dialogue.
  • Fix the formatting of the wikitable.
  • Upload unused models, there are some used in the Kleenex Training level with a bc_ prefix.

Alternate Camo

In the mission The Bog, it is possible to acquire an M21 with a unique camouflage through console commands. Upon further inspection, it appears to be an early version of the Desert camo.

Unseen Weapon Content

  • When the Desert Eagle and M9 are hip fired, their slides move back and reveal their ejector slots, which cannot normally be seen due to the speed at which their slides move.
  • The MP5's normal magazine has a 2D bullet on it that cannot normally be seen due to the speed of the reload animation.
  • The P90 has engraved on the side below the rail "P90 cal 5.7x28", which can only be seen during the first raise animation and empty reload animation but cannot be read due to its placement and the animation being so short.

Unused Weapon Content

While the M249 SAW and RPD do not have any damage drop off in multiplayer, their weapon files still specify damage drop off ranges. Both weapons' damage would start to decrease after 1500 units and hit their minimum damage at 2000 units. These drop off values are different from their values in single player, which are used.

Hidden Level Select

By going into the console and typing /set developer 1, you can access a hidden menu that allows you to select every level in the game regardless of how far you have progressed in the game. In this menu, it shows every level and the build dates for each level.

Longer F.N.G.

The original version of F.N.G. was considerably longer, going through the controls and all the game's features. Sadly, it was truncated late in development, but there's a mod that reinstates the original level.

Among the cut content was one part that would have had Sgt. Newcastle teach you how to use grenades, grenade launchers, and C4 - and because F.N.G. was forcibly made shorter, he remains complete and fully functional. A second part would have Mac teach you the basic moving controls in the obstacle course. All of the associated dialogue is still present.

Interestingly, 2016's Modern Warfare: Remastered brings all this back, for some reason.

In addition, Hangar 2, pictured above, contains an unused training course which can only be seen using noclip. This area is never used in the uncut version, and most of the course has no collision.

Crew Expendable Enemy Placement

On Crew Expendable, the first group of Russian soldiers encountered after going inside the ship have unseen behavior. While they are normally encountered all clustered together at the end of a hallway, prior to being encountered one soldier will idly walk around farther up the hallway. This behavior cannot normally be seen as by the time Soap reaches them they are situated at the end of the hallway. This can be seen at 2:20 in this video.

Unused Cutscene

An unused soundless video called dog_vs_player_load, showing a USMC player being killed by a dog at an unknown (possibly unused) location. In the final game, the USMC never encounter dogs in the campaign.

The video also shows an unused USMC first-person model that is completely gone from the game. The blood and gore effects are also very low-quality, likely putting this at an early point in development.

Michael Carver

A name that appears in the unused mission strings for the cut levels "Descent", "Training", "Designated Training", and "Designated Marksman". It is possible that he was the US Marine protagonist before Paul Jackson, but he was scrapped along with said missions.


In some levels of the campaign, if the player fails to complete a designated task sometimes an event will happen that will complete the task for them. While most of these "failsafes" can normally be encountered, some normally cannot be encountered at all, often times because they are tied to a task that is virtually impossible to fail.

  • On the training level, if the player takes longer than 2 minutes to complete the CQB test the player will die and the mission failed text will read "You were too slow." This cannot normally be encountered as test takes around 20 seconds to complete. A video of this can be seen here.

Unused Miscellaneous Campaign Content

Hidden Water Texture

In various missions, increasing the brightness through console commands reveals that the water texture consists of a texture with numbers in it.

Helicopter Damage

To do:
What level is this (see Youtube video)?

An enemy helicopter on a certain level can be destroyed via a grenade. While this can be done in-game, it cannot normally be encountered as it is very difficult to do. This can be seen here.

Unused Perk

Expose Enemy


A scrapped perk where only its icon remains, code name "specialty_exposeenemy".

Unused Graphics

Unused Create-A-Class Icons

It would seem that the developers originally planned to have the Create-a-Class weapon icons change based on the attachment that the player equipped on it, as the game's files contain a large number of unused Create-a-Class icons for every weapon, each showing the weapon with the attachment connected to it. Some icons have files, but upon opening them the image is blank, indicating that the developers never finished creating these individual icons.

Unused Scopes

To do:
Find the scopes for the Dragunov, R700, and Barrett .50cal.

Due to a programming error, all Sniper Rifles use the M40A3's scope reticle, which leaves several unused scopes in the files.

Also present are all of the faction-specific rifle scope overlay textures from Call of Duty 2 (for the Lee-Enfield, Kar98k, Mosin-Nagant, and Springfield rifles), as well as an unused overlay version of the ACOG scope.

Unused Multiplayer Ranks

Present in the files are 10 unused rank icons for multiplayer.

Prototype rank icon #1 Prototype rank icon #2 Prototype rank icon #3
The first three seem to be early versions of the rank icons.

Prototype rank icon #4 Prototype rank icon #5 Prototype rank icon #6 Prototype rank icon #7 Prototype rank icon #8
The next five appear to be lower-quality versions of the respective existing rank icons. It seems that there were going to be gold versions of the Eagle, Star and Double Bar rank icons.

Prototype rank icon #9 Prototype rank icon #10
The last two are highly similar in style to the used rank icons.

Most of these are also present in Call of Duty: World at War, but aren't used there either.

Regional Differences

To do:
Hi-res screenshots.

For some reason, the German version not only removed the dramatic gore effect upon shooting Zakhaev's hand off in the "One Shot, One Kill" mission, but Arcade Mode is disabled and cannot be unlocked.
