How to fix error code 2901

Error code 2901 essentially prevents you from connecting to the Call of Duty servers. This disallows you from getting into the game and has caused lots of issues recently. This error code seems to appear more frequently when the game is updated, which leads to an uptick in player count. Busy servers can often cause this error code to appear, but what can you do to fix it?

Close application

This is a simple solution but one that works frequently. Simply close out of the application and restart your system or PC to try for a workaround. If the issue is serverside, this won’t always do the trick, but it’s worth trying at first.

Make sure application and system have most recent updates

Since this error happens more frequently when an update goes live, it’s possible you might’ve forgotten to install the latest update. Close out of the game, check for updates, and install them if need be. Then try launching into the game to see if this fixes the error.

Reinstall content packs

On rare occasions, you may need to reinstall content packs to get around the 2901 error code. Modern Warfare 2 allows you to install content in different parts, and some of this content may be corrupted — leading to the error code. Try reinstalling the Multiplayer Pack or the Warzone 2 pack to potentially fix the error.

Modern Warfare 2 Trello

If all else fails, this error is likely an issue on the game’s side and could require you to wait it out. Be sure to check the official Trello board to see if and when issues are addressed.

Does Call of Duty: Modern Warfare 2 have Hardcore mode?

In Call of Duty: Modern Warfare 2, players have access to a wide variety of multiplayer game modes including Team Deathmatch, Search and Destroy, and the new Prisoner Capture. One of the most popular modes in the series is Hardcore, which has been in the series for years. This intense mode removes the HUD and increases damage across the board. But does this mode appear in the new Modern Warfare 2?

Here's what you need to know about the Hardcore mode in Modern Warfare 2.
Does Modern Warfare 2 have a Hardcore mode?
When Modern Warfare 2 first launched, it didn't have a Hardcode mode, much to the disappointment of fans. Instead, the game had a mode called Tier 1, which was basically a rudimentary version of Hardcore mode, with some missing features. For instance, there's no HUD, whatsoever, no hitmarkers, and no killfeed, which made the mode hard to actually play in some cases. Thankfully, Activision finally did add Hardcore more at the start of 2023, replacing the Tier 1 mode from before.

Call of Duty: Modern Warfare III is official and it’s coming this November

Activision has confirmed a November 10 release date for Call of Duty: Modern Warfare III with a teaser trailer following a barrage of leaks.
The shooter, which is going to be a direct sequel to 2022's Modern Warfare II, was the subject of lots of reports and leaks prior to this announcement. Reports from Bloomberg revealed that this game was originally going to be a Modern Warfare II expansion, but it later got upgraded to a full game. Then, over the summer, more game details started to leak before some Monster Energy advertisements revealed the game's title prematurely. Activision coyly acknowledged this leak on Twitter at the time, but finally pulled the curtain back on the project today with a video titled "Modern Warfare III is Coming."
Modern Warfare III is Coming
It begins with some green soundwaves on-screen and a lot of radio chatter in the background. Then, the soundwaves turn from green to red before the perspective then pushes into them, creating a trippy red void. In there, we briefly see waveform images of a snake and Captain Price before he says, "Never bury your enemies alive" over the silhouette of a new character. This is believed to be Vladimir Makarov, the villain of the original Modern Warfare trilogy, who was teased in the post-credit scene for last year's campaign. After all of that, the title Call of Duty: Modern Warfare III is confirmed, as is the release date of November 10.

This date falls right in line with the late October to early November window in which Call of Duty games usually come out. It also places its launch after Microsoft's Activision Blizzard acquisition is expected to be complete, so it looks like this may be the first Call of Duty game released under Microsoft. Other than that date, official details on the game are fairly scarce. Thankfully, we shouldn't have to wait too much longer to learn more.
Call of Duty: Modern Warfare III launches on November 10.
