First of all NS 2 is a great game! And a very nice conversion of CS and SC.

However I was missing the "creepy" atmosphere & wanted to foreground the flashlight.
(e.g. of ALIEN (The Movies), Dead Space (G-Enhancer Mod),etc ...)[/i]

The basic requirement for this MOD is Sweet FX 1.4

SweetFX for NS2 [gsngaming.com] --> many THX to Fatchicken for his work!
(PerformanceLoss: about 5%)

For the "creepy" atmosphere I modified the "SweetFX_settings.txt" a little bit...
--> the following are examples of the Dark Vibrant Look (my favourite):

"Vanilla" Look ........................................................ Dark Vibrant Look

A friend of mine asked me for a less vibrant version...
It's as dark as the other one, but with less colour saturation!
(Vibrance: Intelligently saturates the pixels depending on their original saturation.)

"Vanilla" Look ........................................................ Dark Natural Look

1. Download[gsngaming.com] & Extract SweetFX to your NS2 directory.
2. Choose one of the SweetFX Modifications from the next two sections.
2.1 Copy & paste the whole text of your chosen modification and replace the content of the original "SweetFX-settings.txt" in your game directory with that. Use notepad and don't forget to save the "SweetFX_settings.txt" afterwards.
3. Ready to Play! (Press F12 ingame to switch SweetFX On/Off)

[To UNINSTALL just delete all SweetFX Files from your GameDirectory!]

Game: Natural Selection
SweetFX version: 1.4
Author: CeeJay.dk
Preset: Fatchicken

These are the default settings for SweetFX 1.4
They smoothen jagged edges with SMAA anti-aliasing, sharpen the image with LumaSharpen and make the colors slightly more vibrant with Vibrance.

Please note when tweaking settings that higher numbers does not always equal better (nor does lower).
Finding the best settings for your game and your taste is about finding just the right amount to apply.

If you made a good setttings preset please share it with your friends, on forums and websites,
and/or submit it to the SweetFX Settings Database : http://sfx.thelazy.net/games/
