In the campaign or story mode of a video game, speedrunning refers to the practise of running past (as opposed to killing) opponents to reach checkpoints. In this way the campaign can be completed very quickly with a minimum of fuss.
Speedrunning videos were all over youtube in the Halo 2 days; now it's much harder.
