BlackFire's Mod Ultimate is a stunning and completely customizable Lighting Mod that completely changes the look of all levels of the singleplayer campaign of Crysis, it can adapt to the taste of each user with the push of a button. The goal is not to bring a more relistic lighting, but to bring more life to the game, and encourage people to replay the game, with an innovative look.
The customization of lighting is what really sold it for me, being able to change the different colour levels, dramatic lighting filter just looks amazing.
A very well made mod, and considering it doesn't come at a massive fps hit is just another great point about it, since huge fps drops are deal breakers for a lot of people.
