I've tried and failed to make some weapons but there are two programs to use. Nearinfinity and IEEP, i've heard people claim both are better. i tried ieep cause nearinfinity crashes my computer. i suggest checking out www.teambg.com if you want to start modding

don't care to much for two handed weapons but that is just me

I think two handed weapons are the best for fighter types but thats just me

I went to team BG but couldnt find any weapon thingees

you want to download ieep, and you need vb6 package to make it work

I'm still kicking myself over Carsomyr. >.<
