Hi Panda, welcome to the forums, Id just stick with the trainers for now things like below:
XOIIT's Constant UAV Hack
Insane's MW3 Multi-Trainer [1.9.453]
If you'd like a crosshair on screen all the time to aide you in shooting from the hip and also helps with some scope's - I'd give
Master131 External Crosshair v3 a go
As with all hacks posted on here - " Use at your own risk " - I check here EVERY TIME - YES EVERY TIME - before I play MW3 and use hacks,
just to check if any of the hacks I use have been reported.
these are the one's I use, you could use master131 - MW3 .NET External ESP v3.5 [1.9.453] - which is just awesome !!
personally - I hate aimbots and aimbotters and never use this option - BUT do use the other options (master131 - has done an top job with this !)
the above are just my preferences
use your head when your hacking - dont make it to obvious - dont max your prestige
(say from Level 6 - to prestige 10 lol - ppl can tell by your stats - although these can be hacked to)
Try my suggestions above and see how you go with them - then maybe look more at Injected type hacks - if you want to
if this helps - click the thanks button - cheers
