Customization is a stub. Send in reinforcements. We gotta take it back!
There is a Customization element within the Multiplayer of Homefront. From the Main Multiplayer menu, the player can scroll down to the Armory. This is where the player can customize their classes. There are six immediate classes along with a Vehicle loadout.
Inside the six classes, the player can change there is their Primary Weapon, add an attachment to go with it, and they can add camouflage. However, is should be noted that camo is unlocked at a higher level. Along with the Primary Weapon, there is a slot for a Special Explosive E.G. EMP Grenade. There are also two Purchase slots which can be bought using Battle Points (BP). Finally there is a slot for Infantry Abilities, which are based on a value system.
