Modern Warfare 3 CODMAS: event dates, rewards, and more

By

Call of Duty: Modern Warfare 3 is letting you get in on the holiday spirit early this year with its CODMAS event full of new maps, modes, rewards, and more. This limited-time event has new content to experience all across the Call of Duty suite, from traditional multiplayer to Warzone and Zombies. While you could just experience the holiday cheer, there are a ton of special rewards and things to see before it ends that may never come back to the game. Check out all the details on the CODMAS event so you can write up your wishlist before visiting Santa Gnaws himself when it begins.

The main event of CODMAS is split into three new sets of challenges across multiplayer, zombies, and Warzone. There’s Santa’s Slayground in multiplayer, Slay Ride Resurgence in Warzone, and several individual Santa-themed challenges in Zombies. The former will unlock things like new skins and blueprints, while Zombie challenges will give you random but valuable loot.

You can also look forward to two maps getting a holiday makeover: Shipmpas and Hangover.

Limited-timed modes

Two limited-time modes are available for players, both naughty and nice.

Infectious Holiday is the classic Infected mode but with a Christmas spin. Instead of appearing like traditional zombies, all the infected players will donn the Zombie Santa Skin to hunt down the Operators.

Snowfight is coming in as a more chill version of Gunfight. Rather than begin with a gun as normal, the first two rounds of this mode equip you with nothing but a snowball to chuck at your opponents. Don’t be fooled, though. Someone probably put batteries in there or something because they will still take you down. If you find the rare yellow snowball in the middle of the map, don’t think about it too hard and grab it because it is a one-shot kill weapon! While the game returns to normal at round 3, you can still scoop up snowballs the entire game if you want to embarrass your enemies.

On the Warzone side of things, Slay Ride Resurgence has added festive trees and even Santa himself. If you board the train, you can encounter Saint Nick and put yourself forever on the naughty list by taking him out. It’s all worth it for the loot and exclusive Emblem.

You can also visit one of six Deck the Halls trees that have sprung up on the map to tear open those presents! No need to worry about getting socks — they all contain loot. But don’t get too eager. If you can resist the childlike urge to rip apart the wrapping paper immediately, you and your team can decorate the tree to upgrade it as long as no other teams are in the area. You can bring it from Tier 1 up to a max of 3 to increase the rarity of loot the presents contain.

How to fix packet burst in Modern Warfare 3
A soldier shields themself from an underwater explosion.

The last thing anyone wants to see when booting up a game like Modern Warfare 3 to head online with your friends is to be stopped by an error. Online games are susceptible to all types of problems beyond the player's control, leading to plenty of frustration and disappointment in a possibly ruined experience. While there are more substantial issues that can completely prevent you from playing, seeing the packet burst issue is almost worse because, while it does let you play, you will experience a ton of lag that makes the game essentially unplayable. If you've been struck by a packet burst error in Modern Warfare 3, here are some possible solutions so you can get back to fragging.
How to fix packet burst errors

If you spot a symbol of three squares on the left of your screen while playing Modern Warfare 3, it means you're suffering from a packet burst. This is essentially an error where something is messed up in the communication between your system and the game's servers, resulting in terrible performance. While it could be simply an issue on the server side and not related to you at all, which you can check by looking at the Modern Warfare 3 server status here, there are a few things you can do to potentially fix the issue on your end.

Modern Warfare 3 Zombies: Mercenary Convoy guide
Soldiers in a car driving and shooting zombies.

The old format of Zombies has been left behind in Call of Duty: Modern Warfare 3 in favor of a more open-world, objective-based take on the undead survival game type. This time, you will squad up and drop into a map with specific objectives you can choose to complete to earn tons of XP, while also pushing the narrative forward and unlocking new, more difficult tasks to take on. The early-tier missions are generally very simple, but in Act 1, you will be given the objective to find and destroy a Mercenary Convoy somewhere on the map. This sounds easy enough on paper until you realize you have no idea where this convey is or how to find it. Every run in Zombies risks losing all your hard-earned progress, so we'll lead you to the Mercenary Convoy to take it out before the zombies even know you were there.
How to find the Mercenary Convoy

Your first challenge will be to find this Mercenary Convoy. The problem here is twofold: first is that it isn't marked on your map in any way, and second is that, being a convoy, it is mobile. Once you land, you and your team should find the nearest vehicle and head toward the center of the map. Depending on how the threat levels are on your particular map, you are looking for roads and highways that are around the medium-threat level zone. You will have to patrol these roads until you come across the convoy, which only consists of three vehicles. Once you are in range, it does appear on your map to let you know you've found it.

Modern Warfare 3 Zombies: tips and tricks for MWZ

The mega-popular Zombies mode has never undergone as massive of a restructuring as it has for Call of Duty: Modern Warfare 3. What was originally a round-based, co-op survival mode where you and a team of four gradually powered up, expanded the map, and maybe tried to complete a challenging Easter egg story has become something more of a mix of Zombies and the new DMZ mode from last year's entry.

While there will be plenty that is familiar to Zombies veterans, such as Perk-a-Colas and mystery boxes, you won't be able to rely on your old tactics anymore. Surviving the new Zombies mode is a completely new ballgame in Call of Duty: Modern Warfare 3, but these tips and tricks will help you and your squad survive threats both old and new.
How is Modern Warfare 3 Zombies different than previous entries?
