I've played with 8 other people in a FPSC Multiplayer game, and, trust me, it's loads of fun. It's a bit of a hassle to get running at first, because I had to get everyone to open their ports correctly, and allow FPSC through their firewall, but, the game didn't lag once, and I didn't get any ping problems either, and i'm on diap-up!
Currently, it doesn't support CO-OP, but, the soon-to-be-released X10 will. And, after that, we hope that CO-OP will be backported to the current version. So, eventually, yes, we will have co-op. Won't be for a while though.
Quote: "-Can multiplayer run on a dedicated server?"
Currently, what I believe is that TGC has one server, and every multiplayer FPSC game is hosted on that.
All in all, FPSC is a great development tool.
