Exodus: Grand Melee is a 4x mmorts game with galactic scale pvp campaigns, true galactic empire building/management simulation, and a choice of rts or turn based mech/combined arms combat. Players take control of a mercenary company, customize and expand company assets, bid on contracts for missions from large factions, and battle against each other for control over resources, territory, and politics, in a massive game universe with thousands of persistent battlefields that run in real time, 24 hours a day.
Here are some early screenshots of the Alpha build of the combat engine
