Superbus via Inscientiae

On the floor and the wall of the lobby of the Advanced Biological Research Lab (Biodome Complex) can be seen a logo featuring the Latin phrase "Superbus via Inscientiae" and a DNA double helix in the middle.

The logo and the phrase have been tied to the ARG due to its occurrences near pizza boxes and/or "The Pizza is a LIE!" graffitis in hidden locations throughout the Black Mesa facility.

Earlier in the ARG, when the Code D puzzle was still unsolved, it was theorized that the "Superbus via Inscientiae" phrase could possibly be the 20 character phrase required for a VIC cipher. But this turned out not to be the case.

The logo with the Latin phrase is originally from Half-Life 1 but has been recreated with a higher graphical fidelity in Black Mesa. The phrase has an approximate translation of "arrogance through ignorance". More information about the origin of the logo and the phrase can be found on the Combine Overwiki.

Locations
Below is a table listing the all the locations where the logo is found in both the 2012 mod release and the 2015 Steam Early Access release of Black Mesa.

The locations have been found by searching in all the .vmf source files of the maps for every instance of the decal texture "decals/lab1_flr8d" as well as the model versions of the logo: "models/props_questionableethics/qe_logo_sign.mdl" and "models/props_questionableethics/qe_logo_sign_200.mdl". For the mod release of Black Mesa, the maps were decompiled in order to get the .vmf's. For the Steam release, the original .vmf's for the single player campaign included with the game were used, and just the multiplayer maps were decompiled.

The logo can also be seen on several plasma TVs around in the Biodome Complex. The model file for these are "models/props_questionableethics/qe_tv_plasma.mdl" with the skin texture file containing the logo in "qe_tv_plasma_screen2.vtf". However, these only appear in the Questionable Ethics chapter and are therefore not considered out of the ordinary, and thus not included in the table below.
