Players become lost in a jungle. Upon trying to find a way out players find that they need to set up camp. Being ever aware of the dangers, setting up camp seems to be the only method. The camp starts out basic but players become unable to rest unless the camp can be fortified and cleared. During the day players should collect materials and possible sources of nutrients (which can lead to all kinds of shinanigans.) If the DM judges that they have enough materials players can build various defenses. Wood Fense, Baracade, spiked baracade, crushed rock (for difficult terrain), nets for pit traps, nets for ariel protection, pretty much anything the party can make use of.
