Paper Sheets

You can find and collect paper sheets in the environment. When you have paper sheets in your inventory, open the crafting menue (Shift + I) mark one paper sheet and press "use item". Some paper sheets contain random crafting recipies for stuff like custom leg splints, Ghillie Suits or House upgrade kits. The recipe will be shown directly on the screen, as soon as you close the dialog, you have no possibility the view the recipe again, so write it down for you...
