It's very bad... it's like, well... I can't think of another DLC that is as bad
haha.
It was just a bunch of simulated combat encounters with 0% story additions. The only good thing about it is the view from the command area when you first walk in, so if you can find that on YouTube, you will have experienced all it has to offer.
Here is a still:
This was my single biggest complaint (equal with the last boss dribble) of ME2, I
loved my damn scar!
I think that with EC/Leviathan/Citadel included, the muddiest part of the water is
mostly cleared... mostly.
I personally don't think we will see ME4 until well into 2016, Q2 seems too optimistic to this Eviscerator toting Kiwi Vanguard...
My personal predictions:
E3: ME Trilogy Remaster for Next-Gen/PC + ME4 teaser and official announcement to release on N7 day in both 2015/2016 respectively.
