Ya'll should check this shit out. It's a new fps games similar to dayz and a mix of battlefield where your in a large map (looks like dayz) and you go out hunting others, you can either stick as a team or go solo and kill others so it's like dayz without the zombies.
Here's the description.
Survarium is a free2play MMOFPS game set in the near future. The game focuses on the aftermath of a massive ecological catastrophe on Earth, the reasons behind which are only vaguely known.
Impassable woods advance onto cities from every side, as maddened animals and birds attack industrial complexes, military structures, warehouses and power-plants. Strange plants and mushrooms grow through concrete and steel. Scientists all over the world haplessly try to cope with the anomaly expanding with terrifying speed across the planet. Countries collapse; anarchy spreads throughout the world. Now force dictates who can survive.
Here are some screenshots.
Here it tells you all the roles and I guess clans you can choose(currently)
