This sign is a location marker for a side mission players can access on the planet Promethea. The sign has a fuzzy screen static to help sell the damaged effect and digital display. While not shown here, the static is animated in level. The animated static effect on the screen was done by the technical artist, Caroline Gruber.

There is also a slight normal detail on the cracked screens in order to have the light catch the cracks a bit more.
