Think about it, having the option to rappel down a building. Or even later after they implement helicopters. You could tactically descend or ascend from one. Parachutes would be a great addition to the game. Of course it wouldn't be useful until planes or air travel of some sort was put into the game; It would only make sense when searching an airfield's tower or hangers that you would have some sort of probability of finding one. You could essential craft if you had a blade and something else a make shit net, or a net trap. Or it could have other useful purposes like a fishing snare net, Combine with some logs against a surface for a Make shift lean too Structure that you could stack foliage on, and there's other purposes think about it be creative. On the other hand though Deconstructing it.: Could make rags,rope,and a kinda makeshift backpack. They should also add a Hockey bag option for carrying/storing loot.That way you could carry more then one primary. On top of having another descent size item persistent storage space. Maybe even add some scuba gear. If you add scuba you must add sharks to the ocean though for aggressive AI animal and to deter people from trying to be super sneaky trying to kill people by creeping onto islands,harbors, and boats after if they get implemented, but wait if you have all that you will need a spear gun and a diving knife.Tear gas in the form of a pin throw-able grenade or a launch-able style from a rifle mounted launcher. Maybe being able to find crabs for a source of food that you could cook in a pot that you must fill with water and boil. Soviet Based weapons id like to see would be some sort of Rpg,a Tokarev, a RPK,TM series or PMN mines, PFM mines,MON mines, or maybe even water mines, an SPP-1 underwater pistol and their APS underwater rifle(Maybe some coral and reefs and fish life,possibly more islands?), OR a mortar launcher of some sort like the 82-BM-37, PSM pistol, GP-25 grenade launcher for ak series of assault rifles or something similar, OR a Stechkin automatic pistol. AO-27 rifle.RPO-A Shmel rocket launcher with its various types of ammo it was known for.MSP Groza Silent Pistol,Kolokol-!, IP-2 light machine gun,M249 at a crash site maybe? What if could harvest sea weed for some sort of useful purpose.What about an ultimate rare occasion of running into some npc survivors mostly lonely but once in awhile be in a group/tribe/pocket of survivors. depending where you are on the map changes the probability of running into them. What their attitude would be like would be based on probability factor.Maytbe even an old outpost with a couple of friendly NPC mercenary's that will trade or sell you valuable supplies in a certain secluded town somewhere. Folding razor would be a sweet melee weapon
