Hello All ,I can't unlock weapon in this game ,I don't know how unlock weapon.
Please help me ,I haven't any weapon except the weapon of the base.

(Sorry for My bad English ,I'm french)

earn XP by playing ranked servers..

As you rank up you receive weapon unlocks. There is a bug in the game that can cause you to lose your new weapons, so make sure after you select the new weapon or attachment that you so do while logged into a game server, then exit the game and restart it. Hopefully, Crytek will figure this out soon.

Ok ,Thanx but I haven't anything and I'm lvl 20 ,Can you xplain it? *_*?

You have to spend your weapon unlocks on the customization screen, they do not unlock automatically like they do with Call of Duty

Hope this helps!
