Doing this for unity3D;
Planing on adding some fog/dust, (like I did in spirit of half-life,
the one that I made a smoke sprite, then had it scaled up, had had 3 of them slowly move, you could hardly see them)
In unity I got the scene set up with two pulsing lights (blue and red)
only thing is, the lights pulse at the same time, I don't know how to delay one light, they automatically start!
