with the icons on some of the achievements you can see Dean Ambrose, Kofi Kingston and Jack Swagger are all confirmed to be in the game. Which also means other Shield members will be in the game. and since there is a manger listing on that is on the select a character screen it will be most likely Zeb will be in the game as as well.

Achievements that caught my attention:

Woo Woo Woo!!!
Create a Custom Superstar that is set up with a social account. (Really?)

One of a Kind Superstar
Create a Custom Superstar that uses a Superstar head. (after all these years its back? didnt they stop this in Smackdown 2?)

Sudden death
30 Years of WM - WM 12 - Bret Hart vs. HBK - Reach the time limit with no winner.

The Demon of Death Valley
Defend the Streak - Defeat 30 Superstars in a single match. (Whats this now?)

Excuse me!
WWE Universe - Establish a rivalry. (So this has been fixed? finally)

Finish Them!
Perform an OMG "Shell Shocked" (Single player). (No idea why but im interested)

Can't wait for this game, I wonder what they mean by beat 30 superstars in a single match

^ I'm guessing you just win 30 singles matches?

I think it's the game mode you get to pick from for WM 30


Either face the undertaker in Super Undertaker hard mode...or play as Undertaker and fight off 50 people

Its probably a gauntlet for Taker and you have to go 30-0

there is one I think where you have to go 50-0

That Bret vs HBK one is going to be a drag, having to draw out the match and not go for decisions. This game is shaping up to be awesome
