Best Multiplayer Games - Pls Reas TEXT

These last 2 months ive been searching for a proper online gaming experience.But almost none unlike COD 4 include,

1.the unlocking of guns during LVLing up

2.The unlocking of abilitys (maybe the upgrading for abilitys)

3.any other awsome feature of LVLing.

With These 3 features LVLing is worth it.

Got Any Ideas?

Have......MGO

I prefer games that don't force you to unlock crap on multiplayer, but that's just me.

Resitance 2 has you unlock beserk abilities and customization options.

Warhawk also allows you unlock customization options with "ranks".

MGO also has a type of experience bar that allows you to make your character stronger, have better aim, more endurance; and so forth.
