After being briefly teased last weak, Guild Wars 2's (*inhale*) Living World Season 4: Episode 2 - A Bug in the System has now arrived. It has brought with it a brand new chapter in the currently ongoing story, a large and rather beautiful new map to explore, a new mastery to unlock, a variety of balance changes and cosmetics, and even a new legendary dagger to unlock.

If you're wondering what all of this looks like in-game, wonder no more as ArenaNet has recently posted a brief trailer. I would highly recommend you give it a look as it's one of the best trailers they've created in quite a while, with a special mention going to the sinister cover of "Fear Not This Night" near the end. Have a gander:

There are far too many changes to cover in brief, so if you're interested in all of the details you will find the full patch notes over at the official website. The one thing I will mention, however, is the new health bar control options that greatly improve the gameplay of support/healer roles. In other words, you can now always show party and squad health bars, enlarge so health bars for party, PvP and subgroup members, or if you're so inclined, give all squad members thick health bars so it's easier to keep an eye on them. A minor change in the grand scheme of things, but a highly welcome one regardless!

Have fun with the new storyline, and make sure to check out the recent Developer AMA (Ask Me Anything) on Reddit as it has some rather interesting answers and teasers for future content!
