Interdimensional Rift (A Crossover Feature Discussion)

[Nephalem Vanguard #SV_PureIsBad]

As also a fun idea, considering this is a spiritual successor to Half-Life 1 and 2 I assume, is it possible to add in a big feature to play both Half-Life 1 and 2 maps (making BSP files adaptable for VB), coupled with the NPCs from both games being replaced with the Abiotic Factor NPCs? The first Quake game maps can also be a good option since Half-Life takes its root from the Quake engine. Because New BSPGuy exists, writing a text file of all the entities and weapons can also be an option, as people can edit BSP maps without decompilation. I know New Blood Interactive did the same thing with DUSK, but for the first Half-Life game. The wads and material files are also an important factor. That is up to full consideration, and I am confident that this can attract even more Half-Life fans like myself, like Moths to a light bulb.
