Left4Dead2 Visuals Multihack

Very unfortunate because charm XYZ, ESP, glow or outline do not have the infected visible/not visible color option like the DME charm. So you can't tell whether the infecteds are behind wall or not from far distance.

And it only works on some servers, but not for one particularly. Any chance that some servers have anti hack that works for certain features like ghost ESP but not other?

Use Glow/Outline with custom advanced settings then you can tell if the target is visible. For the anti-ghost-hack problem, yes all Zonemod servers have a plugin called l4d2_noghostcheat.smx (https://github.com/SirPlease/L4D2-Compet.../anticheat), and it blocks ghost info from sending to client so can't be bypassed.

I'm not sure if it's zonemod but it does have Tier 2 weapons and medkits are not removed...etc. Are there some ways to check if a server is using zone mode or ace mode?
