Wulfram is a free multiplayer, action-strategy game. You control the hovertank and destroy enemy bases. You are part of a team, and can help that team win in many different ways. Your able to help build new bases, help place strategic elements that allow spaceships to maneuver, help your frontline tanks by going in with a medic unit and repairing their damage on the battlefield, help the team by rushing enemy bases all alone, or be part of a large group of frontline tanks that battle it out on loads of different servers and maps. The game has a friendly community with good behavior and has trainers to help new players every step of the way... not found in many other games. You just need the patience to master the steep learning curve. One aspect of the game I really enjoy is being able to build up a clan/squad of friends and having a private server to war against other clans. Try it out Here. Its only a small file and easy to install, give it a go
