An old mod for Nightfire made by Norulez which gives the game the look and feel of Battlefield 2.
To my knowledge there aren't any websites still active that have this mod anymore, so I've uploaded it here for anyone who wants to give it a go. Description and preview image from Norulezgaming.webs.com Battlefield 2 Mod. This mod was made by 2GoldenBullet$ in 2007. It is a full mod for nightfire that includes a BF2 menu, BF2 hud, BF2 sounds and more. It is an installer (exe) so all you have to do is download and click next, next, next, until it installs and click finish. It is easily uninstalled by going to the start menu.
