Today i'll make another suggestion, DayZ is a game in which the player must search for items to survive, but there is not this "search". By pressing the "tab", the player sees any item around without even see. Removing the "vicinity" will make players look for items by themselves, lying on the floor, looking shelves, cabinets, tables, refrigerators, under beds...

• Players "hurried" will leave "hidden" supplies behind.
• Only players with a good sense and calm will search for items.
• The time of play will increase, because players will waste some time for search some stuff.
