Gearbox talks more about Aliens: Colonial Marines' unique lighting system

“We spent a lot of our preproduction time making this custom lighting system that plugs into Unreal Engine 3. We had to design something from the ground up that would give us the capability to create… all this tension, to create all these dynamic events and to recreate the look and feel of what we experienced growing up watching [Aliens].” - environment artist Chris Neely

Aliens: Colonial Marines is certainly going to look and sound the part, but I'm starting to get nervous that the gameplay won't actually be all that hot.
