The Ultimate DOOM. Part 1
Just some good ole' DOOM!
Heres a link to the doom wiki page for the sourceport I'm using: https://doomwiki.org/wiki/GZDoom This isn't a download link, but if you want one, just check out the external links on that page. And no, downloading the sourceport is not enough to play the game, you need the base game's data - the sourceport just replaces the executable.
Extra features as explained at the start of the video:
Jumping & crouching - neither are ever used to go somewhere I shouldn't be allowed to, rather to just enhance my combat options.
Mouse freelook w/o autoaim - to make it feel like a 3D shooter.
