People supported you in their own weird way.
Look... most of the weapons you are asking are already in FPSC. You can change some textures to give it another look or ask for people to give you a hand for some stuff.
What you are asking about AI is probably quite easy to do, you just have to learn a bit about scripting.
The problem here is: when people say "This is my idea and I want heaven and hell for free." the immediate thought is: what do you have to offer in return? Level Design? This is what they all do here.
Get your project going, make some nice screenshots, post it on Showcase and try to get some help to the things you are missing. People feel bossed around if someone says they want everything.
And making a basic level takes a couple of hours while doing some nice weapons takes a couple of days, see the point?
Good luck with your game, hope to see some screenshots soon.

p.s.: btw, who is Official Owner?
I'm pretty sure I know everything. Doubts are something rare in me and I am never wrong, as this signature can prove.
