With DOOM Eternal hitting hard this November, some of you are probably hankering for something to keep you busy. You could go back to 2016’s DOOM, but if you really want to get into the spirit of things, Sargeant Mark IV has released v21 Gold of his acclaimed Brutal DOOM mod, complete with trailer.

Technically, it was released back in May, but it needed a kickass trailer to really show it off.

According to Sargeant Mark IV, he wasn’t able to show all of the new features of this update with this trailer (which is set to music by the amazing Andrew Hulshult). “If I were to make a trailer listing every new feature that has been added from v20b to v21 I would probably need to use a Dream Theather[sic] album,” explains the man himself.

For all of that, you’d best check out the changelog, which predictably lists a whack of stuff. To get in on all of this, you’ll need a full version of classic DOOM. The instructions on how to install the mod are pretty easy and straightforward, so you’ll be painting the walls with demon blood in no time.

And in case you want choice (which we all do), there’s now an option to change the amount of blood/gore you’ll be seeing as you gun down enemies. It comes in four varieties: Less; Normal; Extra; and Jesus That’s a Lot. You can guess what version most of us will be using.
