List of Bugs in the Campaign

List of Bugs in the Campaign
Kill or Secure - Stay With Your Squad Bug Kill or Secure - Ghost Stuck in Helicopter Bug Recon by Fire - Vehicle Guards Not Leaving Violence and Timing - Can't Board Price's APC Truck Bug Prison Break - Rope Down Bug Fix

Kill or Secure - Stay With Your Squad Bug

In the Kill or Secure mission, there are reports of players getting stuck on the first objective which asks Soap to stay with his squad. During this portion, Ghost will not move even after the dialogue scenes and the mission will not progress.

How to Fix Bug

To fix this bug, players can either load from the last checkpoint or restart the game. The player should also try going directly to the pinpointed marker as this may solve the problem.

Another way to fix this bug is by verifying the game file's integrity. Doing so will help detect any corrupted files in the game that needs fixing. Steps on how to access local files will vary depending on the platform you are playing in.

Stay With Your Squad Bug

Kill or Secure - Ghost Stuck in Helicopter Bug

After clearing out the second house in the Kill or Secure mission, Soap and Ghost will go to the crash site to provide support to the downed squadmates. Some players reported that Ghost will stop moving after the third wave of attacks, causing the mission to be at a standstill.

How to Fix Bug

To avoid encountering this bug, players can stay close to Ghost during the encounter in the crash site. This method can also be used for problems that involves Ghost staying stationary. Another option would be to load from the last checkpoint or restart the mission if the problem persists.

Recon by Fire - Vehicle Guards Not Leaving

During the Recon by Fire mission, the player will encounter enemy reinforcements that will patrol the entrance to the garagae and housing buildings. Some players have encountered a bug wherein the vehicle guards will maintain a stationary position, making it difficult to sneak past them.

How to Fix Bug

The most effective way of dealing with this bug is by simply going on the offensive and eliminating all hostiles in the area. Gaz can utilize smoke grenades to limit the vision of enemies and maximize the thermal hybrid optic of the Victus XMR.

Vehicle Guards Not Leaving Bug

Violence and Timing - Can't Board Price's APC Truck Bug

The Violence and Timing mission will have Gaz driving vehicles and engaging hostiles to reach the front of an enemy convoy. In one of the objectives, Price will task Gaz to board his APC truck and wield a grenade launcher. However, some players are reporting that a bug occurs during this sequence, disallowing them to board the APC truck and failing the mission.

How to Fix Bug

Reports from players indicate that simply restarting to the last checkpoint does not fully solve the problem. Thus, it is recommended to restart the entire mission in order to advance past this objective. If the bug still persists, re-launching Modern Warfare 2 might solve the issue.

Although it is only the campaign, Modern Warfare 2 will still require players to connect to online services. Ensuring that you have a stable internet connection might also help prevent the bug.

Prison Break - Rope Down Bug Fix

Players are reporting that they are experiencing issues with the last objective in the Prison Break mission. The bug prevents players from using the rope and descending down the wall to complete the mission.

How to Fix Bug

To fix this bug, the player can avoid NPCs on the platform by staying on the right side of the wall. If this method does not work, restarting the mission might also solve the problem.

Check for Modern Warfare 2 Updates

If you do not have automatic updates enabled, you can manually enable it to catch all the patches and hotfixes that have been shipped to Modern Warfare 2. With this turned off, you will have to manually start each download before you can sit down and play.

• On Steam, right click Modern Warfare 2 in your library and select Properties > Updates > Always Keep Game Up to Date.
• On Battle.net, go to the Modern Warfare 2 game page in your library and select the Gear Button > Check for Updates to see if new ones can be downloaded.

• Steam: Right click Modern Warfare 2 in your library and select Properties > Local Files > Verify Integrity of Game Cache. Steam will scan and re-download any corrupt game files it finds.
• Battle.net: Go to the Modern Warfare 2 game page in your library and select the Gear Button > Scan and Repair. Click on Begin Scan and wait for the game to repair itself.

Free Up Additional Storage Space

All of the newer Call of Duty titles take up a lot of storage space. Make sure you have enough space before trying to install the game. If you find yourself not having enough space to start updates afterwards, you will have to free up storage space in order to keep playing the game.

Opt to Turn On Texture Streaming

To shave off some required storage space for Modern Warfare 2, players can opt to turn on Texture Streaming from the Settings menu. This allows you to stream high fidelity textures from the CoD servers rather than having them take up space in your PC or console. If you have a good internet connection, you can opt into this feature to save storage space.
