Date of release: May 2015 – limit removing port req.
The Unknown Chasm is the basis for this level. It has never been released anywhere other than on Doomworld as it was an entry for a contest there. I thought it was about time I featured it on my homepage as well.
The are many differences between this level and the orignal. For starters it’s not for Doom II but for Doom and there are now an open sky instead of a rocky ceiling.
A third version of The Unknown Chasm and this level can be found in Monument. This version is a step up from the original with much better gameplay and highly upgraded visuals.
