I would be sincerely flattered. Please go right ahead.
Is there a place where I can see progress as you develop it?
Not as of right now, but I do intend to start posting my progress on Github and maybe Youtube once I have something presentable.
This is actually my very first foray into Doom modding, so I'm learning as I go. My MMX1 TC idea is admittedly way out of my capabilities as of yet, so it's a project I want to get done on the long term. I'm focusing on modding the player character for now.
I have quite a bit of the player sound and visual aspects done, so right now, my goal is to get this part done, and then I'll get to the gameplay part. Only when that's done I'll start thinking about the TC campaign. I do intend to release the standalone gameplay mod though.
Still, if you're curious, I can certainly show you how it's going so far. It's still very barebones with no gameplay alterations whatsoever, but it's still something. I'll send you a .pk3 file if you want to take a look, though I'll only be able to do so tomorrow night.
Thank you so much for allowing me to use your mod as reference! After posting my initial comment, I downloaded it and spent quite a few hours blasting through the Doom 2 campaign. Absurdly fun stuff, can't wait to try it with other mapsets.
