With this update installed your renegade will load maps significantly
faster and in Co-Op servers you can hear and complete objectives that
require special actions such as pressing E on objects to activate them.
Also in a lot of servers you will be able to use the sound commands
and much more.
This update must be installed into your Renegade folder, not your Data.
Also close Renegade before attempting to install this update!
