Until the release of the Doom source code (Dec. 23, 1997) it was impossible to connect several Doom demos together (or at least, we are not aware of a way it could be done - maybe someone else knows...).

But with the release of the source code it's possible to connect LMPs across levels with only a small modification. This leads to a series of new Doom multilevel runs when each level is recorded separately from a savegame and then the LMPs are connected to the full run.

(Demos are not connected within levels - only across levels. There is a way to connect demos within levels, but we are sticking with QdQ's tradition, also we believe that would ruin much of the fun.)

So far we've done both Ultimate Doom and Doom2 quick. There is a long history of speed-running in Doom. If you want to check out other demos, then the centre for all Doom speed-running is the COMPET-N site.
