In OnPluginStart:

HookEvent("player_death", Event_PlayerDeath, EventHookMode_Pre);

Event_PlayerDeath function:

public Action:Event_PlayerDeath(Handle:event, const String:name[], bool:dontBroadcast) {
    SetEventInt(event, "revenge", 1);
    return Plugin_Continue;
}

The downside of this is that every time you kill or get killed, you hear the revenge sound. It gets old quick.
