On this new video you can see Brutal Doom 64 being played with Vanilla Doom maps. I play some minutes of Doom 1, Doom 2 and Final Doom Evilution to demonstrate how the mod will be playable without requiring the Doom 64 maps, and acting as a gameplay mod just like regular Brutal Doom.
You can also see some new sound effects, new blood decals, and other stuff going on.
I am planning to release the first version of BD64 this month before Halloween. An announcement trailer will come up soon.
