Just when you thought the universe couldn’t get any bigger in Mass Effect 3, Bioware/EA comes out of nowhere and announces a new multiplayer expansion (called Mass Effect 3: Retaliation) that lands on October 9th.

But what is included in this, the biggest multiplayer expansion yet, you may ask? Well, there are 6 new maps, 16 new characters, new enemy type: The Collectors, new weapons to collect, new “challenge” feature, and each map will receive “environmental hazards” to make things a little tougher.

For more details, continue reading on after the break!

So most of the new stuff is self-explanatory except for these “Challenges”. So here is the official details from Bioware themselves:

Think you are the best soldier in the Alliance? Make sure to track your progress in the new “Challenges” database. Complete various multiplayer assignments and feats of strength to unlock titles and banners to display in-game, and then compare your progress against your friend.

How does it work?

The “Challenges” database tracks various in-game statistics, such as your N7 Typhoon usage. To earn challenge points, you’ll need to complete mini-goals. For example, accumulate 140,000 points while using the Typhoon in multiplayer and you’ll be rewarded with 10 challenge points.
Challenge points are used to unlock cool in-game multiplayer bonuses, such as new titles and banners. Want other players to know that you’re a Council Operative? You can do that. Want to be the envy of your friends with a flashy new banner to display in the player lobby? You can do that, too!

Challenge points lead to unlocks, and unlocks allow you to personalize your multiplayer experience. Now, you’ve got some work to do, Soldier!

Can you say Borderlands 2 anyone?

So again, this huge expansion is due out on October 9th for everyone!
