2 Questions!

I will thank you if you answer those please:

1) I got a bug, in-game, Zombie, Multiplayer and Singleplayer I cannot see my Reticle of the Sight i am using. I tried all sights, none of them works. I got Intel Hd 4000 graphics, please if someone can help me or someone here maybe makes a file which may work or something like that?

2) Is there any level hack? I mean, there was one for MW3 that I used, but now on Black Ops 2 it's really slow leveling too, please tell me is there?

I would just double check all of you in game settings.

That's a bug for the Intel HD 4000. You can't do anything about it.
And no, there is no level hack, it gives an error, makes you unbale to play.
