> Try our luck. It can't be any worse than the stairwell full of corpses.
You go around the back. The big, brown, metal door appears to be open, and in this light you can see that it's rusted into place.
Looking outside, you see the building's parking lot. It is also overgrown, even more so than the street.
You don't see any corpses immediately. Most of the cars are still here, though, including your roommate's.
The fastest ways around the building--that is, the alleys between this building and the next ones over--are choked with waist-high grass and weeds. You'll have to wade through it no matter what you do, going this way.
Would you rather go around the west side of the building or the east? The west side looks less overgrown, but there's also a chain link fence between the buildings on that side that you'd probably need to climb.
