Recently, GoldSrc speedrunner “quadrazid“, previously famous for his 20 minute Half-Life 1 speedrun, uploaded a video of what he calls “Half-Life Backwarding”, which is exactly what it is.

In the short video, quadazid attempts to make his way through various Half-Life levels such as the Hazard Course as fast as he can, but this time facing backwards.

If you thought normal Half-Life speedruns are crazy enough, then this has just taken it to a whole new level.
