[L4D2]Explosions can set survivors fly
 

I remember there is a plugin can make survivor fly just like hit by tank punch when they were blown up. Type of explosion include boomer's dead, gas tank explosion, etc.
But I forgot the name of the plug-in, does anyone remember that? I tried to use the Search, but I still couldn't find it.

• Bile Blast: Due to bile and methane building up, when the Boomer dies the pressure releases causing a shockwave to damage and send Survivors flying.
