Even though its a just a skinning/sound tweak edit, at least its a start. This is how AvP Original and AvP Gold Edition community modding started out. The community found ways to do client sided skins and sound editing so you could at least enjoy some customization on your side. Remember
lv426.com, planetavp, avpnews, etc? All the major community sites had client-sided skins and sounds download sections. Plus, if you share your tweaks with your friends you can all play together and enjoy your tweaks.
This is a good thing. Very cool to see that at least this much is possible for now.
Reminds me of the old AvP Original/AvP Gold Edition days!
