Call of Duty: Modern Warfare 4 (MW4) is a fan-made mod for Call of Duty 4: Modern Warfare, not an official release. The campaign takes roughly 2 to 3 hours to beat on Normal difficulty, depending on your skill and whether you explore for hidden intel. Below is the full mission list and a breakdown of what each level involves.
Formula
The calculator above works out your average pace and speed for a given distance and time. The formulas are:
Pace (min/km) = Total Time (minutes) / Distance (km)
Speed (km/h) = Distance (km) / (Total Time (hours))
Where t is the total time in minutes, d is the distance in kilometers, and the speed formula converts minutes to hours by dividing by 60.
Worked Example
Using the default values: time = 50 minutes, distance = 10 km.
Pace = 50 / 10 = 5.00 min/km
Speed = 10 / (50/60) = 10 / 0.8333 = 12.00 km/h
So you run at 5 minutes per kilometer, which is 12 km/h.
Understanding the Campaign Length
The MW4 mod was released in 2017 as a single-player expansion for Call of Duty 4. It features 7 missions, each designed to be played in one sitting. The total playtime is short compared to official Call of Duty campaigns, but the mod focuses on intense, linear combat encounters rather than open-ended exploration.
If you play on Veteran difficulty, expect to die frequently and reload checkpoints, which can push the total time to 4 hours or more. On Recruit, you might finish in under 2 hours.
Full Mission List
Here are all 7 missions in order, as they appear in the campaign:
- Prologue – A short tutorial mission that introduces basic movement and shooting.
- Urban Warfare – Fight through a city district, clearing buildings and alleys.
- Desert Storm – A vehicle section where you operate a tank across open terrain.
- Night Raid – Stealth-oriented mission with night vision goggles; avoid detection where possible.
- Chemical Plant – Infiltrate a facility and destroy equipment while facing heavy resistance.
- Highway Chase – A scripted sequence on a highway, with enemies in vehicles and on foot.
- Final Stand – The climactic battle in a fortified compound; survive waves of enemies and complete the objective.
Each mission typically takes 15–30 minutes, depending on difficulty and playstyle.
How to Install and Play
MW4 is a mod, so you need a copy of Call of Duty 4: Modern Warfare (the original 2007 game) on PC. The mod is distributed as a standalone installer that replaces the base game’s files. To install:
- Download the MW4 mod from a reputable modding site (e.g., Mod DB).
- Run the installer and point it to your Call of Duty 4 directory.
- Launch the game; the mod will load automatically.
- If you want to revert to the original campaign, back up your files before installing.
Note that the mod is not compatible with the remastered version (Call of Duty: Modern Warfare Remastered) because that game has a different engine and file structure.
Common Problems and Fixes
Players often encounter a few issues with MW4:
- Game crashes on startup – This usually happens if you have an incompatible version of Call of Duty 4 (e.g., 1.7 vs 1.8). Update your game to the latest patch before installing the mod.
- Missing textures or black screens – Verify that your graphics drivers are up to date and that the mod files were extracted correctly.
- Cannot save progress – The mod may disable autosaves in some missions. Use quicksaves (F5) frequently.
- Audio glitches – Reduce the sound quality in the game settings if you hear crackling.
If problems persist, check the mod’s official forum thread for known issues and community fixes.
Comparing MW4 to Official Campaigns
MW4’s length is much shorter than the official Call of Duty 4 campaign, which takes about 6–8 hours. The mod also lacks the cinematic polish and voice acting of the original, but it offers a taste of new missions for players who have exhausted the base game. If you’re looking for a longer experience, consider playing the original campaign or other fan mods like Call of Duty: Modern Warfare 3 (the fan-made one, not the official game).
