Yes, but only with specially made "limited use" lines. No such are included and won't be.

So I can make something like 4 people fall scream together in local server?

It is possible to make that.

scene "scenes/Gambler/LedgeHangFall02.vcd" then All iMT_PlayerDeathScream foo:0 -0.00000001

I managed to make all people fall scream but they didn't start vocalizing exactly the same time, if I change the "-0.000000001" to "0", all the other survivors will wait until the first line end(which is they will only scream after I finish screaming). Or I tried to remove the scene part to fix this, leaving only "All iMT_PlayerDeathScream foo:0 -0.00000001" but seems didn't work too. So how can I fix it?

Hi ion, can you make ion's vocalizer with Admin System Radial Menus Complete. It would be cool if your vocalizer mod has admin system radial menus complete but sadly it's not featured. The original author of Admin System Radial Menus Complete is David7097. So, you might have to give David7097 credit if try to put Admin System Radial Menus Complete in your mod. So, you will have to make an another mod of ion's vocalizer with Admin System Radial Menus Complete and people will bind (any key) "+mouse_menu ASRMa" or bind (any key) "+mouse_menu ASRMb" in order to use that radial menu. It would be great if I can use special lines from your vocalizer and use radial admin system at the same time.

I think better solution would be to use some add-on with client menus for Admin System, like Admin Menu 2.0 for example. That way you can use the vocalizer and Admin System through client menus without conflict.

By the way, you should've started a new discussion because it's unrelated to this discussion topic.
