My mod has been released. Here are the most changes for the demo:
New Skins for US, desert and woodland by 7game
All weapons are improved, more accurate.
All maps are supported 16, 32, 64.
There are some new maps, Not by me. Credits are when you load the map.
New sounds for weapons, vehicles and explosions.
Some new effects.
Remember, this is a demo. I don't now if it works. But on my pc it does.
