John Connor, the leader of the worldwide human Resistance is MIA, so as a human commander it is up to you to rebuild humanity’s military force by finding and recruiting survivors to your cause and stop the machines from reactivating Skynet. Or alternately you can betray humanity and join the machine regiments. There are six different classes of units in each side that you can control in the game and they range from Infantry to Siege units. Each side is able to select from 24 different units, which can be used in online Multiplayer battles, or in massive clan PvP matches where you join up with allies to defeat the other side. The game also features Single-Player missions that allows players to win special loot and bonuses and there is a crafting system where you can create new weapons.
