Colored lighting! Romero couldn’t believe what he was seeing. The setting was a dungeonlike military level, but when the gamer fired his gun, the yellow blast of the ammunition cast a corresponding yellow glow as it sailed down the walls. It was subtle, but when Romero saw the dynamic colored lighting, it was a moment just like that one back at Softdisk when he saw Dangerous Dave in Copyright Infringement for the first time. “Holy fuck,” he muttered. Carmack had done it again.
