First thing I made was an "actor" for 173. ("actors" are Doom's version of entity since everything is coded and defined the same way).

I then ran a quick test before I adjusted the sprites to test the speed and behavior on other actors. I've tweaked it a few times since this video, but over all I've made 173 incredibly aggressive.

Once that got done, I went ahead and worked on the level. But there was a bit of a problem. Doom can't support a randomly generated level like the current game does, so as a solution to this, I'm making an incredibly vague and featureless level. This is to replicate that lost feeling of not knowing where to go. In a nutshell, crap tons of copy and paste. Here's a screen shot of the current level progress.

As i progressed, this slowly started to become my own mod, in a sense. I would take some SCP's from SCP:CB or add my own (My own as in one i made myself, and not ripped/copied from SCP:CB). SCP-789-j was an SCP i threw in without knowing it was already done.

Yes, that was Nicholas Cage. and he eats your butt if you hit him.
Anyways, I came here to show off the progress behind this and, to be honest, bring some attention to myself, but there's no shame in that! If you want to play this mod yourself, you'll need two things. The newest version of the Zdoom engine:
http://zdoom.org/Download, and a purchased IWAD of Doom 2 (IWADS are the level packages that contain the non-engine coding and level sets), which is only $5 on steam, $2.49 thanks to the holiday sale
and here's the current demo file you'll need to play: https://www.dropbox.com/s/k9jngcba6rna6 ... mo%204.pk3
AS I later made progress with this, the multiplayer engine for doom (Zandronum) doesn't support some of the scripts used in my mod, so it'll be a matter of time until it catches up. But it still has multiplayer spawns points for when that comes.
As a heads up, there is a NSFW image in there, but it's pretty well hidden. If you do find it, please refer to it as "tiffany", so no one else has the surprise spoiled ;)
Feel free to throw in your own suggestions for SCP's, or level tweaks and such. If you are adequate with how the Doom/ZDoom engine works, you can also submit your own SCP or sprite sheet, and I'll be more than happy to see if I can implement it.
