We have a new feature coming in Patch 6.1 that’ll allow you to send out Tweets directly to your Twitter feed while playing World of Warcraft. It includes the ability to send out text-only Tweets; easily take, crop, and Tweet out in-game screenshots; and let your friends know about your recent accomplishments.

Welcome to the first in an ongoing series of programming- and engineering-focused articles that, over time, will cover some of the technical nuts and bolts that go into creating and running World of Warcraft.

Each expansion brings improvements to the dungeon and raid experiences, and Warlords of Draenor is certainly no different. Let's briefly go over some of the dungeon and raid content that we’re planning to release the day the expansion is available, and then go into some of the systems changes that will define how they're played.

While the major focus of Patch 5.4: Siege of Orgrimmar is the Alliance and Horde taking the fight to Garrosh, players will also have a new land to discover, far away from what’s going down in Durotar . . . and this new land is like no other before it.

We’ve got some new stuff coming to the Pet Store, and we wanted to give everyone a quick sneak peek. Obviously, the Pet Store has been the place where we sell pets and mounts, but we’ve come up with some new types of cosmetic goodies, including some fun new little toys and Transmogrifiables.

With 5.2 fast approaching I’ve been wanting to get my thoughts together on how I should be playing in the last couple weeks before the patch. Are there any reps I should catch up on; do I need to worry about spending currencies or upgrading items; and just in general what do I need to start doing now to maximize my play time before and after the patch releases?

First days at any event are always a life-drainer. Despite thinking I’d be heading out for an after party last night, my eyelids were heavy and brain mushy, so it ended up being an early evening with room service and a found-footage horror movie. I’m glad, though, because I was up early, feeling good, and ready to catch the second day’s Arena matches as soon as they began. With only a few remaining before heading into the final four, the two North American teams -- Evil Geniuses and Bring It -- continued to look strong, with Korea’s LG-IM and Europe’s Yaspresents and I’m Just Being Honest fighting for the remaining spots.

Shanghai taxis are better than a cup of coffee – or ten. My morning cab races through downtown streets over painted lines that mean nothing here, passing just inches from cars and pedestrians, and honking for both excellent and seemingly no-good reasons every few seconds. You just have to put your head down and hope for the best, and that act of blocking the world out and praying the next second won’t be your last is exactly what the World of Warcraft Arena and StarCraft II players will be feeling every moment they’re on-stage this weekend.

Challenge Modes are a new feature in Mists of Pandaria that allows coordinated 5-player groups to jump into Heroic dungeons and attempt to set time-trial records. These blindingly fast times are displayed for all to see, but if being famous on the interwebz wasn't enough, the groups who can achieve gold medals are also awarded with unique gear looks for use in Transmogrification-with a twist.

Leading up to the release of Mists of Pandaria, we hosted a 12 day journey on Facebook that included character bios, cover art, wallpapers, and videos to get people amped to play the new expansion. Now that we’re all busy leveling our new pandaren, monks, and 85’s to 90, we thought we’d be real good pals and gather it all up for y’all in one spot. Enjoy!

With the release of Patch 5.0.4, a number of features and changes that aren’t strictly in the continent of Pandaria will be added to the game. I’ve drummed up this guide (with the help of a lot of other people) to ensure you’re prepared for the patch, aware of how it will impact your characters and experience, and ultimately get you into and enjoying the improvements the patch brings as quickly as possible.

The Battle.net World Championship taking place in Shanghai this November will be the culmination of more than 30 StarCraft II World Championship Series tournaments around the world.

With all of the great coverage coming out today on the upcoming expansion, we thought it’d be fun to take some of the details we’ve been revealing and relate them in practical terms. One of our main goals in this expansion is making sure that no matter what day of the week it is, and regardless of your experience or progression, that when you log in you can make meaningful progress toward advancing or customizing your character.

With the 4.3 patch we'll be introducing some changes to the way Valor Points (VP) are obtained, as well as the items that they can purchase.

Adventurers will be tested like never before in World of Warcraft patch 4.3 as they take on Deathwing and his minions, emerging from the conflict with powerful new treasures. Please enjoy this preview of the druid tier 13 armor set, as well as a visual guide to tiers 1 through 12 for Transmogrification purposes.

You’ve been asking for it, and we were listening. In patch 4.3 you’ll be able to customise the appearance of your weapons and armor like never before.

World of Warcraft update 4.2, Rage of the Firelands, will introduce the first new raid tier in Cataclysm, and with that it will also introduce the first conversion from Valor Points to Justice Points. For anyone running Heroics and raids, this is important information to ensure you spend your points wisely before release of the patch.

We’re excited to present the first-ever video BlizzCast, now in beautiful full-motion 2D! (Don't forget to wear your 2D glasses.) We’ve also jam-packed this episode with juicy information on World of Warcraft patch 4.2.

In patch 4.1 we’ll be introducing a new system to the Dungeon Finder intended to lower queue times, named Call to Arms. This system will automatically detect which class role is currently the least represented in the queue, and offer them additional rewards for entering the Dungeon Finder queue and completing a random level 85 heroic dungeon.

BlizzCon presents an opportunity for real-life tailors and engineers to take up their needle and thread, their cardboard and spray paint, to create amazingly realistic recreations of their favorite Blizzard characters and creatures. After this year’s costume contest, we invited the winners to write an article on the art of costume-craft for us to share with the community.
