DropItemsBeforeDying
This is a server only mod to make you drop all items that you carry (clothes, backpacks, weapons or tools) right before you die. No matter how long dead body will be persisted, your dropped items lifetime values are the one from server economy configs (types.xml). You can make items in certain categories to last longer on the ground as you like. When a player dies, his stuff (dropped items) will be persisted even after server restarts.
Server owners:
1. Copy @DropItemsBeforeDying folder to your root DayZServer folder.
2. Copy the key file provided to your DayZServer keys folder.
3. Add launch parameter: -mod=@DropItemsBeforeDying.
Clients are not required to have this mod, if they do have, it is harmless anyway.
