As you want,
https://forums.alliedmods.net/attach...4&d=1286304664 It's a public plugin. Mr. Connor didn't add a cvar or similiar to toggle it on/off, this can probably be done by resetting the values to default from what the plugin changes or use Orpheu supercede return.
Though when I tried to do Orpheu supercede/ignore (return supercede to cvar = 0) it gives me a tag mismatch error (probably because it doesn't work under that kind of function), so method 2 as what I'm doing right now is to get the default stats of fuser2 & maxspeed of what he replaced them with and then reset it back to default, when you're using the cvar since method 1 didn't work for me, example amx_axn_bhop 0/1. I simply wanna add a cvar, these are the 2 methods I know of, method 1 didn't work for me.
