Yeah, that's what I figured.[blackout]She presses the button, kills herself, Shepard is knocked out, wakes up with 30 minutes to go.[/blackout]
Definitely Arrival. Overlord is a fun little distraction but has no bearing on the main plot (at least as far as I can tell. Arrival is basically the epilogue to ME2/prologue to ME3.
Since I'm about at the halfway point of ME2 right now, with a few loyalty missions still undone and haven't finished with the Collector IFF mission, if I get Arrival when should I do it? Maybe I should wait until I'm already at the end of the game to activate this mission?
You rate everything an 8/10.
It even improved my opinion of Liara, although I'm still not sure I completely buy her switch from archaeologist to seedy info broker.
You can check back later and see the results.
