But why would you even bother, master131 has an amazing MW3 External ESP in C#!
Apart from the fact that you can never have too many hacks, master131's release no longer supports Windows XP, whereas mine does.
How easy is it for this to be detected?
It is completely external, and only reads from the game memory, meaning it's unlikely to be detected anytime soon.
It doesn't work in Private Match/Dedicated Servers!
Restart the hack.
It's slowing down my machine/I get excessive flickering
Due to the XP-Compatible render mode, flickering is unavoidable, but can be reduced by tweaking the refresh rate in the config file. Turning down the line thickness may also help.
Do I need any runtime libraries?
Only .NET 3.5/4.0.
