Beta3 Level Theme is a Level Theme exclusive to Beta3. It is essentially textures that were not found in the final release of the game.
These can also be alternative versions of textures. Depending on the method used, these may be the textures used in a custom level instead of the base game.
The Slipgate textures are relatively inconsistent between levels. Most contain the version found in the final game, while some hold an animated alternate version. Lava also uses the textures from the main game for the most part, though there are exceptions such as E3M3: the Tomb of Terror. The Elder World skybox is also similarly inconsistent, only being found in E4M2: The Tower of Despair and E4M7: Azure Agony.
Most levels in the final version of the game have exit signs. These do not exist in the Beta3 variants.
