Call of Duty 3 (The one that came out over a decade ago) still does not have any mods made for it. There is a way to give yourself god mode and some other cheats though, but that doesn't really count since its editing the button-mapping config file. Nobody has made a mod menu for the game or EVEN a button-mapping mod menu (people at least did that for COD2). The only solution I found to change your score in ranked multiplayer is you have to be the host and then use Peeker to detect changing values and hope you find the ones (like kills assists etc.) that increase your score. You cannot modify your score directly as there is no value for it, the score you see displayed is your kills + assists +, etc. so you have to modify those instead. Yeah, it wasn't really popular back in the day and it surely isn't now. But for a COD game, you'd at least think that somebody would like to claim to be the first one to create a mod menu for a game that's in the COD series. I've spent hours looking for any COD 3 mods and I have not been able to find any (excluding the button mapping iso mods). If there are mods for this game that allow you to modify your score/rank easily, please share.
