Another update to my 3 part level pack, Breach. This time, I changed enemy placement and enemy type depending on the chosen difficulty, aligned textures, and generally polished the levels. I know this is all I've been uploading, but I want the levels to be at their best. I'm working on another level pack as well, and I feel like it will be better than Breach. Watch out for Facilitarium.
Unfortunately, I was unable to fulfill l.strain's request of adding images. It seems that multiple images can only be uploaded with a mod, not just a file/addon.
these images will suffice! ;)
