/*QUAKED env_shake (1 0.5 0) (-8 -8 -8) (8 8 8) EVS_GLOBAL
Causes an earthquake/shaking effect when triggered.

-------- KEYS --------
"targetname" : Name
"target" : Target when triggered.
"killtarget" : Target to kill when triggered.
"radius" : Radius of the quake/shake effect.
"amplitude" : Amplitude of the effect.
"duration" : Duration of the effect in seconds.
"frequency" : The frequency of the shake.

-------- SPAWNFLAGS --------
EVS_GLOBAL : Affect all clients, ignoring "radius" entirely.

-------- TRIVIA --------
This entity was introduced in Half-Life (1998).
