Universe at War: Earth Assault will employ a unique balance system called "Tactical Dynamics" that allows players to retrain and customize units in the midst of battle to better cope with enemy forces and tactical situations. Weaponry and defenses can be modified in true real-time to take advantage of constantly shifting battlefield conditions. Fully customizable tech trees will allow players to control the development of technologies that they deem key to victory. Battles in Universe at War: Earth Assault will be large in scope and take place in malleable and deforming environments. Deadly sci-fi weapons and alien powers will allow players to destroy cities and whole territories on a global scale. Because the world of Universe at War: Earth Assault is persistent, players will be able to revisit previous battlegrounds to find them still smoldering in ruins. Featuring innovative multiplayer modes inspired by popular massively multiplayer online games and competitive online playable titles, Universe at War: Earth Assault will give players achievements, rewards, and medals in a balanced environment to further encourage players to move forward in the game. Players from around the world will battle in persistent-style online campaigns for ultimate faction supremacy across a virtual representation of the Earth.
