Here is a 2min video of the prototype map, Des Neros. This map is the only map of its kind that can alter its own light source depending on where you are in the map. The map also displays pulse and cascade lighting effects unique to Aftermath. The new lighting engine allows the Des Neros map to change the way in how it casts light. You get to see rays, pulsing, light intensity variance and more.

Please note there are several bugs with the video quality (sound issues). Other programs were running in the background. Map has very little to no lag otherwise. (less info)
