Well, that was fast. Only a little over 24 hours have passed since Aliens: Colonial Marines emerged from its dark alcove, but graphics mods are already becoming available. Two such offerings are the DirectX 10 (opens in new tab) and SweetFX (opens in new tab) add-ons which spruce up shadows, lighting, and color palettes for something a bit more reminiscent of the films' murky tones and cool hues.
The DirectX 10 mod softens shadows a bit and tweaks illumination and to bounce and reflect off weapon textures and other surfaces. Installing SweetFX provides a less subtle effect: deeper color saturation, a sharpened texture filter, stronger shadows, and a faint blue gradient for outdoor areas. The latter looks a little extreme in some indoor areas, but it's definitely a darker flavor than the default visuals.
Though Colonial Marines wasn't the Aliens game reboot fans desired for years (opens in new tab) , it's still nice to see a few dedicated modders pushing for graphical excellence regardless of the quality of the game. Have a look at some sample shots below for both DirectX 10 and SweetFX, and head to Mod DB (opens in new tab) and DSOGaming (opens in new tab) to download each one.
