I've just launched our newest feature: a comprehensive item and crafting database for DayZ! After spending the past couple weeks working on this, I'm very happy to be able to show it off now. To help get you started, here's some of the best parts.
You can see a list of food and drink with all of the nutritional information right there with it. You can use this to estimate how much you need to eat to reach the healthy status, for example.
On each item's page, there's always a box on the right side with all kinds of details about the item. What type of details depends on the type of item; weapons show damage info, food shows nutrition info, clothes show armor and capacity info, and so on. This is meant to make it easy to look up an item and know exactly where to look to find what you want to know.
Some types of items are related to others. For example, weapons have attachments, and crafting recipes use and create items. These relations are shown in tabs, along with comments and screenshots. This makes it easy to see things like what attachments can go on your gun, what magazines it uses, and what can be crafted with an item.
There's a ton of information to see here, and it's all linked with the map, too. On any item page, there's a "Find on map" button that will take you to the map with only spawns that you can find that item at marked. Similarly, on the map itself, all of the items in the loot tables link back to the database.
Now that the database is live, improvements to the map are my priority. First up on the list is a topographic version with contour lines. I know a lot of people have been waiting for it, and now it's coming soon; I'm aiming for sometime next week.
