A two map .WAD in which you find and infiltrate a hidden cliffside base. (Do not expect this to be on the scale of my Turok 2 mods)
A couple levels for Doom II that center on navigating a canyon and infiltrating a secret base hidden in the cliffs. Now... where does this all sound familiar? Started before 2020 and gradually worked on-and-off of until now.
That was pretty fun but I recommend using buttons as level exit instead of doors because players may unintentionally exit a level like I did.
