Stuck in Cemetary maze

[tukhachevsky]

Hello, I've scoured the internet for answers to this, but I don't think it's been addressed.
I am in the cemetary maze, I dropped through the floor, got stuck in the room with the upgrade cannisters, managed to get out by pulling the lever hidden in the wall.
However now I am stuck in the maze and can't find the exit. Any suggestions?

Never mind, got out, wow, almost ran out of biocells there. Brutal!
