Well, you won't really get far with a budget of 'free'. Headshots in multiplayer are already possible. And as far as
voice chat goes, you can use an external voice chat system such as SKYPE (free) while you're playing.
However, if you're willing to pay to make your games better,
FPSC IP is available for purchase, and is targeted specifically to enhance multiplayer games.
Quote: "What is FPSC IP?
FPSC IP is a program designed to make the FPSC multiplayer games more user friendly and more professional.
It is fully customisable and there are no pop-ups and logos.
You can use it in commercial and non-commercial games as well
What does it do?
It allows game developers who make multiplayer games with FPSC to add multiplayer lobbies with chat(available now!), multiple levels(host chooses), and it also means that everyone who wants to play the game does NOT have to know everybody's IP address!
Multiplayer Lobby: A area where the players go to when they join a game, if the host has already started the game then the new player can join. If the host has not started the game they can chat to the other players and then play.
Multiple Levels: You make multiple levels(up to 1000!) for the game and FPSC IP allows the host to select a level to play. All players then play the selected level.
Feature Pack 1: Connection speed checking, host kicking and frag/time limit changing are some of the things included in this feature pack."
