the gun is looking good. i would suggest you to only do placeholder models right now and try to get a little prototype running as soon as possible. so you can get a feeling whats possible. especially with multiplayer - that is the hardest part if you plan doing it over the internet. have a look at locoweeds tutorials for a simple lan shooter and read other tutorials on how to otpimize it for the net.
in this thread. there are a number of ways you can do this. i think icex even supports splitting a huge terrain in several .mdl files after modeling and painting it but iam not shure if it works well with the latest A6.
