Collector

Collector is a novelty speedrunning playstyle that originated in the Czech speedrunning community. The style initially involved the collection of all items on a level, but the current rules for this category are:
 * Demos must be recorded with (Ultra-Violence);
 * Play in no monsters mode
 * Exit with all weapons & keys picked up

The category is not accepted on Compet-n but Collector demos are available from the Doom Speed Demo Archive.
