I have downloaded a GMOD addon pack and I took the sounds from it and now I have implemented it in Empires. I think it makes the jeep sound much better, to see how awesome it is play this: http://dl.dropbox.com/u/6575036/jeep-sound-preview.mp3 To install, download and extract and overwrite to your Empires root directory: http://dl.dropbox.com/u/6575036/jeep-engine.zip
No that addon was PHX3 but my GMOD crashes when I use that, could be because I'm using a cracked GMOD but you know.
They seem a bit off ingame, but I still use them, because they sound nice even if they don't seem to match the volume of everything else.
Volume do you mean that like it doesn't sound like other vehicle engines or literally it's not loud enough.
I think we should save this for 3 phase , it sounds funny when you are climbing the hill with 5mph while the engine sounds like you are flying with 100 mph.
