Finished up the basic behavior for Survivors. Survivor camps are placed around the level. Every so often a Survivor may spawn at a camp. They will be harassed by zombies. If you rescue them by clearing the zombies near them they will cheer for you and drop an item. If you have found a 2 way radio you will receive a distress signal when a survivor spawns. If you have also found the compass you will be provided on on screen indicator leading you to the survivor. Needs a lot of polish but this is a good enough first pass.
