Joining a clan can really give you a leg-up in the game. They can give you advice if needed, and you work together to get more items.
Clan Level[]
The Clan's level will be on the same tab as Trials. You can earn clan experience by completing clan quests. I have no idea what the benefits are to leveling up the Clan, aside from placement on the Leaderboard under Rating..
Trials[]
There are 20 Trials to complete as a clan within a certain time period. I'm not sure, but I think they are random when they reset. Holding your mouse over unfinished Trials will show you how much you have contributed, and the clan member who has contributed the most at the time. Each finished Trial shows the name of the Clan member who contributed the most to that specific Trial. You won't be able to contribute to certain crafting Trials if you haven't unlocked those items in the Workshop.
Some examples of Trials would be something like "Kill 'Infected Civil' with 'Kitchen Knife': 88 times", or "Craft 'Sewing Kit': 48 times", or "Loot Pile of trash: 103 times".
Members[]
Here you can see what members are in your clan, their level, rank within the clan, and the last time they entered the game.
Rewards[]
Boxes earned through trials show up here. Opening them puts whatever item in your inventory. If your inventory is full, you won't be able to open one until you have space.
Raids[]
If your clan completes at least 14 of the 20 Trials, an event will open on the map called Army Cache. The symbol is red and the Danger level is 5 skulls. All clan members that are more than two days old may participate in fighting the Elite Zombie. The Elite Zombie has 65000 Hp, and damage done to it is collective. You can attack the Elite as many times as you want. There is a time limit to defeat him. Fighting him does wear down weapons and armor, but when he kills you, you don't lose any items and are sent back to the village with 50 Hp.
