The Create-A-Class system from previous Call of Duty games has been replaced in Ghosts multiplayer with "Create-A-Soldier". The idea remains the same, but this time you get to customize 10 different soldiers for your squad.
Each soldier in your squad has his or her own loadout, unlocks and level. As you play multiplayer with your soldiers, they gain levels and once a soldier reaches level 60, he or she Prestiges. Prestiging a soldier doesn't reset the soldiers' progress like in previous Call of Duty games.
You gain one Prestige level for your account for each soldier you are able to Prestige. With 10 soldiers you can gain up to 10 Prestige levels in COD: Ghosts.
Each soldiers gender, head, helmet, and uniform can be can be customized. There are over 20,000 possible combinations, which allow you to create the soldier you've always wanted.
All the hard work you've put into customizing, playing and Prestiging your squad can be put to use in the Squads game mode. Squads Mode is for all skill levels and offers a variety of gameplay modes to choose from - solo and co-op.
Your progress in Squads Mode counts towards multiplayer, so you'll be earning XP and ranking up.
As you level your soldiers, you earn "Squad Points". They are pretty much the same as CoD Points from Black Ops and work as in-game currency. Squad Points are global and each one of your soldiers contributes to the total amount.
Squad Points can be used to purchase new weapons, equipment, perks, etc. in any particular order for your soldiers. There are no level requirements - as long as you have enough points, you can unlock the desired item and use it.
