The following are the best downloads available for the game, so far anyway. In my opinion, if you dont have these numerous (2) applications, then you will never fully experience what this game has to offer. Chances are the you probably downloaded these already, but if you haven't then I highly suggest that yo do.

This is the GameSpy arcade software.  This makes it a lot easier to connect to Elite Force servers, by listing them, showing you who's in each server, there individual pings, and even lets you chat with other players.  This can also help you to connect to other games such as Hasbro's 'Frogger' and Raven's 'Rainbow Six' (if you own these)  **Keep in mind that this will only list servers using the "Protocol 23" file or "1.1 Patch", which you can get below**

This is the '1.1 patch' or the 'protocol 23' file.  This fixes many little bugs that the original version had, such as characters getting stuck together, a character getting stuck in a wall on away missions, or the game freezing during cut scenes, it also fixes the Multi-Player by leaps and bounds.  After downloading this file myself, I can't imagine playing the game without it, trust me on this one!
These files are in '.zip' format, if you dont have a program that can unzip files you can download WinZip or as I prefer ZipCentral  wich is free and easier to use, remember if you have any questions, you can reach me by clicking here.
