Quote@aclarkbr90 - the first encounter happened in one of the many alleys of this village, behind this building, the Garage. The Garage is located towards the south between broken horn storehouse and Dr. Teneb's. From what you know, there are Imperial troopers sweeping through the entirety of the resettlement camp. One of the access points to get out of the camp (usually) has been an exit to the northwest, but from what you recently learned from the Imperial commlink, there is a blockade set up there. The camp has been in chaos over the last few minutes, so it's hard to tell what all is going on. Also, there aren't any tunnels - the infrastructure for the camp is minimal at best.
@Kymrel - the buildings are indeed very tightly packed and you may be able to move building to building over the rooftops, but there are some main roads that you would still need to cross. One other consideration is that you may also be spotted by a TIE or some such.
