Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Halo is one of the least customizable games I have ever played--the Combat Evolved version doesn't even have any cheats! The best change I was able to make to my config file was getting my 6800gt to use Antistropic filtering, but there's no way to remove weapon from FOV.
Unless someone knows something I don't, but I've tried something similar and I'm pretty sure it's impossible.
Not in the config file, there is a seperate program that lets you adjust fov in game, and lets you play third person if you like. To remove the weapon, you would have to swap the texture of the weapon with a clear shader. Also what do you mean least customizable? If it was so limiting, then how would some friends of mine make a Halo 2 mod so exact, they were given the front page on bungie.com for it?
