Before - I didn't, now - I know!
I found a working hack for Need for Speed World, I'm so excited to finally see something that works.
I've never been able to hack something online. If you didn't know NFS World is an online game, and online means it's much harder to hack something not like in single player where you just fire up cheat engine and change values.
Enough with the chit chat, here are the both hacks. (image is from their webiste)
I've managed to get both of them working without any hassle.
Download by clicking on Need for Speed World Hacks
Download them, select game .exe and push launch game, then log in to your account and press F5 and after a few minutes you should be set up with the points/money you wanted to hack.
Thanks for reading!
