Stuck at GMS

[Hety]

Stuck at fisrt two floors of GMS and that damned door. How do i get lower?

Do you mean at the entrance to the caverns with two big doors?

If yes then you just need to talk to sentry (guy behind the fence) and he'll open the door for you (and after few seconds of wait - second one). If you're going back from caverns you just need to use the card key slot near the outer door.

Hope it helps.

SPOILER ALERT!

There's a trap door in the bottom corner of the map on the second level. The key to open it is in the central room of that level.
