Currently im working on lighting, making them shootable would be a major boost the the game engine. I have basic lighting as you can see from the demo on www.blitzcoder.com but I want them shootable to make the engine lighting finally complete.
Shootable lights would certainly add a new aspect to the game. I can imagine creeping past security drones (those not equipped with infrared, that is ;)) by shooting out a hallway full of lights. Could make for some extremely tense moments.
