The Factions
The game includes three playable factions. Each has its own unique style and army.
United Civilized States: UCS for short, consists of the American continents. Their society relies heavily on machinery and robotics, and is ruled by an Artificial Intelligence. Machines do all tasks for the humans and as a result the population is lazy and hedonistic. Their army consists of Mecha without human pilots. When playing as the UCS, the player takes the role of a commander working for the President but more directly to GOLAN and another AI called NEO. The UCS has long been at war with the Eurasian Dynasty. The main weapon of the UCS is the Plasma Cannon and the larger Heavy Plasma Cannons. While very powerful, shields can stop plasma before it can make it to the hull of target vehicles. However, it should be noted that with enough plasma (doesn't really take much) will eat through the shields quickly and allow quick destruction of everything.
Eurasian Dynasty: ED for short, controls Europe and Asia. They are ruled by a descendent of Genghis Khan and seem to follow old Soviet ideology. They are somewhat primitive (by 22nd Century standards) at first, relying on 21st century vehicles and weapons, such as tanks and helicopters. They do however have some advanced technology in the form of the Laser cannon and the Ion cannon. The ED dual 120 cannons are very powerful and can also punch through shields, a very useful property in the end game.
Lunar Corporation: LC for short, are descendants of lunar colonists. Since 2084, they severed contact with the Earth when it became apparent that a full-scale nuclear war was about to occur. Since then they have lived peacefully on the Moon. Because of their isolation from the wars of Earth, their society has evolved into a pacifist form. The technologies of the LC are far more advanced than that of the other two factions. The main weapon platform of the LC is the hovercraft. Not having been at war for many years; the LC military machine is almost non-existent. They catch on quickly however, and build some of the more exotic weapons of the game including the Electro-cannon, which emits electricity, much like lightning, to destroy targets (Please note that the units do not need power like buildings; they recharge themselves and are purely self-sufficient) The Sonic-cannon, which emits a moderately powerful radial effect that damages all enemies around it. Another thing to note is that the LC mostly consists of females.
