Despite the age, Half-Life is a game that many set their sights on, mainly for the challenge that is speedrunning. You know, the thing where people try to beat a game as fast as humanly possible, with or without scripts. And loads of bunny hops and grenade jumps. Loads of ‘em.
Using a mod that restores Half-Life to its original 2001 version, a group of people has after 4 years of preparation and practice managed to beat the world record speedrun of 27 minutes, with a whopping 20 minutes and 41 seconds clear time.
