Most records have been done on the Hammer of Thyrion source port. It is not identical in gameplay code compared to original. But there hasn't been strict version rules for this game so far.

I've been working on a speedrun focused source port with some features like speedometer added in. Goal is to make its gameplay identical to original. It's a fork based on Hammer of Thyrion. I added a link to it on the Resources-page.

Nice run with the Paladin class!

Hey!

Added in a 2-player co-op category. It's any class + any class, so you get to choose whichever player classes are the fastest. Objective is to finish game on any difficulty level. Video and/or demofile for submission. 'Hammer of Thyrion' source port or the original game are both fine (as in singleplayer categories).

I'm not that knowledgeable how co-op works in this game, haven't tried it myself. I know it works somewhat like in Quake. :) Do tell if the co-op category rules need some clarifying.

Have fun running the game if you're still planning to!
