Well, if ESP was something easy to do, I'd go ahead and try my hand at it for ya.
But......... I have no idea where to start.
I think the best thing for you to do in this type of scene is not to ask others for help, or to provide something, but to try to figure it out on your own. There's not many people willing to just hand out something, or help others out.
If I knew how to do it, I'd help you out in heartbeat, bro.
But if you want to know how to make LK work online, I can give you the code, and tell you where to edit the PBO.
PM me if you want the info.
But be advised, you still need to bypass sigchecks on servers that require it.
