The Rachni Queen Returns

So here we are, bummin' around caves, burnin' webs and eggs and weird alien computer barriers and shit.

... wait, what was that last one? Who the hell put that around here?

Anyway, Grunt and buddies are able to get through because we just took out that barrier.

Thanks, pal.

Shepard et all find a narrow passage and crawl through it. On the other side:

There's a fight that we go through to drop all the barriers. Hey, can you figure out what's behind the barriers?

(Ahem.)

Fuckin'a, we took care of her in Mass Effect 1! ... actually, if you kill the rachni queen in ME1, I'm pretty sure her stunt double appears here.

This is a choice that affects your war assets. Here's how I understand it:

• If the rachni queen survived Mass Effect 1 and you let her live here, you get rachni workers to work on the crucible, worth 100 points.
• If the rachni queen survived Mass Effect 1 and you let her die here, you get Arlak, worth 25 points.
• If you save the stunt double queen, you get both Arlak company AND workers for 125 points, but after a few missions she goes nuts and knocks 100 off your war assets.
• You probably still get Arlak company for 25 points if you kill the stunt double, but I couldn't prove that one in court.

Honestly, though, these side missions don't affect your final score too much, I promise you're not going to be kicking yourself for 75 points in the end. Pick what you want.

Me, I'm going to paragon this shit:

Grunt shows up and gets us out:
