cod4 uses mmorpg mechanics

Best part in COD4? The multiplayer actually, the “role-playing” dimension: costumization features based on a XP system. I guess some game mechanics are here to stay. The multiplayer reward system (the challenges) is also new. You have all the rush and fun from the multiplayer battlezones combined with  individual  achievements  and  XP progression which unlocks upgrades for weapons and special abilities. So, you can use premade classes (i.e. sniper, etc.) or create a class (actually, you can create several) and choose it’s weapons and special abilities. While playing online, you complete challenges and gain XP, you level up and unlock new weapons and abilities… seems familiar? But I want to choose my char face and gender!!!!!!!
