The first part of this 33 map campaign (meaning the first 10 levels) is complete, It should be quite a pleasurable and challenging experience with a decent amount of exploration. If you want to give it a try, you won't regret it and this won't be a waste of your time. Be sure to find as many secrets as possible, tread lightly, and use all the cover you are provided with. If not, you will die faster than you could ever imagine.
If you don't like what I provided so far, be sure you give your feedback! This is still a beta and I have plenty of time to polish it. I will try to release the full version when Ali's Brutal Doom 0.7b is released.
I was planning on releasing the full map-pack in June with ABD v0.7b, although work on the mod itself is time-consuming so, I will try to release a few maps when the new version is released.
Regarding the video above, many improvements have been made to the mod and the maps so the final product will not look much like what's in the video.
