Okay, I've killed the whacked out doctor, and I've got the key. I've left the surgical area and I'm trying to get back to the medical pavilion. I'm supposed to, right?
Trouble is, the passageway has been damaged. The door is busted. Now what!?
By the way, this game is as addictive as Plasmids! I'm not used to this type of game (horror)...I usually like the military stuff, but Holy Smokes! Talk about atmosphere! It's pretty damn scary!.
Anyway, any help would be appreciated. Thanks.

u are in a underwater tube right? atlas mentions smething bout alot of the tubes breaking? the way u came in is blocked?

Go left

and i agree, this game got pretty damn scary at times

Okay Grem, so I just smash the glass? Hmm...that means I swim outta there?
Okay, let me get my trusty wrench and try it. Thanks!

There is no swimming in the game. Check your map (accessed by pressing "Back" on your controller). If you see any gray/brownish areas, those are areas you need to go to or haven't accessed yet. There is also a bright red arrow that shows where you are in the map, as well as a star with the word "Goal" to show you where you need to end up.

Ah...that did it. When Grem mentioned, "go left", I thought he meant through the water. I hadn't even seen that left turn until Seraph mentioned the grey areas!
Thanks guys...I'd still be walking back and forth through that tube if ya' hadn't helped! Gets more and more intense as it goes along, doesn't it?

Agreed, glad to help. Also I'd like to point out that the quest arrow and map help a hell of a lot when playing this game, as it is easy to get lost in some of Rapture's more interesting areas and completely forget about the main storyline. Keep checking the map, especially if you want to see everything.
