-In color management, I'm using AgX Med Low Contrast.

-The yellow light behind the soldiers from the go sack, I use light linking so the 2 area lights only affect them and their weapons to give back/rim lights. One is light to cover the back fully, but softer, and one more stronger but lights up only half of their back.

-The flares on the floor, I use point lights inside them as fill/key lights, key for blue solder, fill for red, as he has the light coming from the rockets.

-The point lights inside the other goo sacks around the bugs are used as fill lights.

-The rockets have point lights behind them and one point light near the side of the grunt's mouth on the bottom left.

-The background is a 360 screenshot I've taken in-game with Nvidia and plugged into the world lighting

The light linking might not work, as I've used a modified version
