Root help!

[Acclaimed esq]

There's a building, basically right in the middle, and the building next to it has a tree coming out of it, and there's two humanz guarding it. There's all these garage doors on the building, and doors with rails on them. And, there's no opening to the building.

EDIT: I got it. If anybody else is having problems, there is a door around back that you can blow up with a molotov or any exploding bottle. Then there's 3 little roots inside.

.....and if you don't have any bottles with you there's a car just near by... i parked it outside the door and shot the gas tank. Took the door out nicely.
