Stuck in Assault on Dark Athena, My fault or Game's?

[Kamahl_FoK]

(360 version, by the way) I'm in the room where apparently the lady whose name slips my mind at the moment says something about "Want to play a game? I'll win by proxy" or something, and then you're forced to take down a large number of drones plus one regular merc. I remember that you entered the 'fight' by dropping down, and then someone called in to her over the intercom and it started. My problem is that they're all dead, and nothing is happening. I see a terminal that I've tried to use but no option is being presented, and I've been looking for alternative solutions for a while. I'm trying to get the Hard achievement on my first playthrough, hence why I'm reluctant to restart the whole game if this is some game-breaking glitch Starbreeze failed to catch in their testing. Am I supposed to contact the old marine from here? Or is there some clever escape that I'm overlooking?
I also can't just restart the fight because I used the Nanomeds in the room, and it check-pointed me for it.

A better question is; Can I just restart the chapter from the menu select on Hard, and it'll still give me the achievement when I complete the game?

Im stuck in the same exact spot. Did you ever figure it out? What's up with it?

[A Greensquirrel]

If you figure it out send a message to gamer tag A_GreenSquirrel. Or Ill be stuck there forever.

There is a com station where the merc called in, you climb some crates to get to it, there you contact Dacher, then a locked door opens down below.

If this is the terminal you are talking about, then I guess it is a glitch.

[Kamahl_FoK]

It was a glitch, I just reloaded the whole chapter on hard and maintained my hard mode progress until the end of the game.

Everyone in the room must be killed before the intercom starts working.

Don't think I could've used the Nanomeds if anyone were left.
