Note: Our group was short a melee tank type.
Open the door: get attacked by "golems". A very tough fight; we barely scraped through by the skin of our HPs.
Walk around the corner: get shot by sniper girl. We eventually knocked her out and talked to her.
Go up the stairs: watch as two of our characters get eaten by the flower, one of whom died before we took the plant out.
Look into the next room: another encounter starts with no McGuffin in sight. With most of our resources used and down a character, we decided to run.
