Just finished a run with my Vanguard on the Xbox. That was enjoyable.

My thoughts:
Likes- Story and presentation. Brilliant cutscenes, inwardly lol'ed at how many times the poor Commander gets knocked around in this DLC, loved how Shep actually seems distraught at failing to warn the Batarian colonists in time both on the asteroid and back in the med bay. The desperation in Shep's voice really immersed me in the frantic "gotta stop the Reapers, gotta deal with idiot scientist, gotta get off this rock" feel. And though I hate Kenson for her betrayal, I can't help but feel sorry for her in the same way I felt sorry for Saren.
- The gauntlet around Object Rho was crazy fun. I died halfway through, but still fun, especially with Kenson and the Reaper voice taunting you throughout.
- Admiral Hackett on the Normandy. I love his "not sure this is a Cerberus vessel anymore, anyway" with the innocent side glance.
- I also really appreciate that there will be big consequences for all the things (and people) Shep has blown up in order to accomplish his/her mission. Also love that this conversation was with Hackett, whose commanding presence I can't praise more. How proud I was to state I'd gladly stand trial after this was over and hear Hackett tell me he was glad I hadn't lost my sense of honor. No, sir, Paragon Shep through and through.
Dislikes- I didn't know I could stealth the rescue part until I looked at the achievements (which I didn't for fear of spoilers). Not sure if that's more my fault or if some indication could've been given beforehand to be more stealthy. I'm sure it'll be a piece of cake for my Infiltrator Shep, anyway.
- The little bar for Kenson's health/Rho's power grid/proximity to the comm tower partially blocked my radar on the HUD. A tad annoying. Maybe put the bar somewhere else in ME3?

- The hand-waved "Shepard's totally fine after having a Reaper artifact implant visions in his/her mind." It's just odd to me that the lore has made such a big deal out of indoctrination, yet Shep can come out of a direct vision upload plus two days near Object Rho without any serious issues. I assumed that's why Kenson's people kept Shepard captive all that time, to work at indoctrinating the Commander to their side. At the end of the DLC, I was expecting an ominous "there may be side-effects, so stay on your toes," but there wasn't. I hope this is touched on later - Shep's exposure to the artifact could even be mentioned in a quick line in ME3.
- I would have liked a more distinct boss fight for the end of the mission, like VI David and Shadow Broker. YMIR Mechs I've been killing for a long time; they're not that interesting anymore. A good boss showdown would've ended the DLC on a higher note, IMO.
Overall, I'd give it 8/10. Solid mission, got my money's worth, can't wait for ME3.
