I'm still waiting for some dope fresh news on this
Ok, I have the guts of a stand-alone engine working with in-built tools for editing maps, particles, etc, so modding can now be done within the game. There are still many Doom scripts that need to be re-written, but the core BoD functionality is all there.
As it stands, the Barb can use multiple weapons (including bow) + attacks & combos, he can interact with levers, torches, etc, and pick up items. The other 'player' chars need to be done, but it's very time consuming to add the appropriate footstep, armour, clothing, and grunt sounds to every animation for every character. The same needs to be done for the enemies. I have done 99% of the work for the Ork, Mino, & Troll, and about 50% of the other enemies.
I don't want to release anything without a decent playable map, and that could take the best part of a year to make. The BoD textures still need to be converted to Doom materials with 'normal' and 'specular' maps, before mapping even starts. 'Bladeghost' on D3World was going to replicate some BoD maps, but he is working full time on his 'Prometheus' mod.
