Summary
Traditionally, eachWorld of Warcraftexpansion has at least three content updates. These content updates add new dungeons, a new raid, and a new zone to the world of Azeroth. In the case of World of Warcraft: The War Within, the first content update was announced as World of Warcraft: Undermine(d).
Undermine(d) is an update chock full with Goblin ingenuity. Players will adventure into the Undermine in search of plunder, glory, and a little bit of revenge - all things that Goblins enjoy! Curious about what will be added? These are some of the most exciting features that will be added to the game in the Undermine(d) update.

9Undermine Zone
Way Down Under The Ground
Half the fun of a new update is seeing the zone created for the update. The Undermine seems like it is shaping up to be one of the greats already. Undermine is a zone filled with everything a Goblin could want.
It’s run by the many Goblin cartels, and serves as a place for Goblins of all kinds to trade and sell (hopefully mostly sell) their goods and services. Goblins haven’t had an update focused on them since their introduction in Cataclysm, making this a very special update indeed. Hop into Undermine to experience the true G.L.T. energy (Gambling, tinkering, laundry).

8Cartel Renown System
Get In Good With The Goblins
If you know anything about Goblins, you’ll know that they love forming cartels. Bilgewater, Steamweedle, Blackwater, and Venture - all of these cartels have fought and scrambled to beat each other. In Undermine, it seems like players will be able to earn favor with the various cartels and use them for their own purposes.
Much like with the three factions in the Severed Thread, players will be able to select a cartel each week to work for. By earning renown with these cartels, players will be able to unlock cosmetics and abilities. Who will you side with?

7D.R.I.V.E.
True Goblin Engineering
If you know anything about Goblins, you’ll know that they love to invent things. Their inventions aren’t always the most safe, or practical, or even…functional, but the D.R.I.V.E system doesn’t have this problem at all. You know, probably.
The D.R.I.V.E system is how you will get around Undermine in style. The new mount, the G-99 Breakneck, is a ground mount with fully customizable stats. This is a first for ground mounts in the series. The G-99 Breakneck can be customized for different uses, but it is primarily built for sweet, sweet speed. It can also be painted different colors, fixed up with new wheels, and given different horns.

6New Mounts
Going With Goblins
Besides the D.R.I.V.E mount, there are other mounts that are to be added to the game in the Undermine(d) update. Most notable among these mounts is the mechanical Gobtrotter, which will be rewarded to those who complete the Season of Delves. This is timed content, so make sure to focus on delves if you wish to unlock it.
Other mounts will no doubt include rewards from the various raid tiers, as well as drops from rares and dungeons. While no information has been released about these yet, there will be at least a handful of mounts to add to your collection.

5Operation: Floodgate Dungeon
Open The Floodgates
No update would be complete without a brand-new dungeon for players to sink their teeth into. Mythic+ is such a huge part of World of Warcraft that it would almost be impossible not to adda new dungeonin the update. This update’s dungeon is known as Operation: Floodgate.
This dungeon revolves around stopping villainous (er, more than usual) Goblins. Players will fight Big M.O.M.M.A., the Demolition Duo, Swampface, and Geezle Gigazap in a madrush to stop Gallywix from destroying the Waterworks Dam. Stoping Gallywix is half the fun of this updae, so Operation: Floodgate is sure to be a blast.

4New Delves
Delve Into Delves
One of the most praised features of The War Within was the addition of delves. Delves are content that can be done solo or with friends that serve as less intense versions of dungeons, while also adding some puzzles. Two delves have been announced for the Undermine(d) update. While there isn’t a ton of information about what these delves will involve, they will no doubt be as fun as the others.
This update will also add a Tank spec to Bran Bronzebeard, the faithful companion of all solo-delves. This has been a requested feature, and it will make delves much easier for those who main healing specs.

3Liberation of Undermine Raid
The Fall Of The Prince
If you have been playinga Goblin characterfor any length of time, you will know abouthim. Trade Prince Gallywix has been a thorn in the side of every Goblin character since he betrayed them and ruined their chances to be Trade Prince. (If you haven’t played throughthe Goblin starting area, we recommend it.)
The Liberation of Undermine raid will see the players finally defeating that cowardly Trade Prince. While this battle will no doubt be rewarding for all players, it will hold a special place in the hearts of Goblins everywhere. This is anoldgrudge, and finally some debts will be paid in this raid.

2PvP Arena Map
LFG (Looking For Goblins)
The first rule about Goblin Fight Club?Alwaystalk about Goblin Fight Club. For those who love nothing more than to bash players' heads in, Undermine(d) is introducing a brand new PvP Arena Map to the game.
There isn’t a ton of details about what kind of match will be played in this Arena yet, but the map itself looks like some sort of madcap gladiator ring in the heart of Undermine. Considering how much Goblins like both profit and chaos, it can be imagined that this might be some sort of wild fight to the death. Are you not entertained!?

1Tier Sets
Truly Fast Fashion
Every new raid brings with it a new batch of tier sets. The Undermine(d) update will bring some changes to how tier sets work - there is now both roles and specialization based bonuses to the tier sets depending on what you are playing.
The theming around these tier sets' designs seems to be very angular and metallic, which makes sense considering the metalic nature of Undermine. It seems like a bit of a missed opportunity to not have the sets be made in the Goblin style, but this allows the sets to have that classic vibe tier sets often do.
