Thanks for uploading a solo map. They so rare nowadays. I have not played heretic so I dunno how well you copied E1M1. There are some cosmetic annoyances in the map (lack of shading), but gameplay wise I find few things to complain about. It is a short and easy level. Like first levels in general are.
Heretical Cyborg is VikingBoyBilly's first complete single player map. It is also customized for co-operative play. It is modeled after the first map of Heretic, E1M1 "The Docks," and is an attempt at remaking a Doom-engine map into the Marathon Infinity Engine.
It started off as an entry for Kill Them All: Volume IV, but the polygon count went up too high. Instead of letting it go to waste, here is this completed standalone map for you to play.
