Super Mario Bros. is one of the most popular video games ever, but few people can complete it as fast as US gamer Brad Myers, better known as darbian.
Released in 1985, Super Mario Bros. has gone on to become one of the biggest selling games of all time with 40.24 million copies sold.
darbian though is king when it comes to this game having broken the record for Fastest completion of Super Mario Bros. yet again with a blink-and-you'll-miss-it time of 4 min 56.528 sec..
It's a special game for darbian, who's played it a whopping 27,474 times: "Super Mario Bros. was the first video game that I can remember playing, so it's really fun to return to it as an adult to learn about it at a much deeper level."
Set on 20 October 2017, Darbian shaved more than three tenths of a second off his previous time, 4 min 56.878 sec, which he described as "unassailable" when he set it in October 2016.
Darbian has a history of beating records on the game which he says are impossible.
In January 2016 he said the fastest anyone could complete the run (minus tools assistance) was 4 min 57 sec: he's since gone under that time twice.
Does darbian think his latest record can be beaten? Well maybe judging by this tweet:
The Super Mario Bros. World Record is now 4:56.528!!! I'm taking a break from the game for a bit again, but be sure to keep an eye on these streamers as any of them could challenge this record any day! @somewes@Kosmicd12@Winnerisyou@StuckInAPlatehttps://t.co/LY6I7g8Byr— darbian (@darbianSRL) October 21, 2017
And he's not ruling out another attempt in the future either.
"I'm sure I will, I don't know when though. I might try in a few weeks, or maybe early 2018, or sometime after that - it depends when it appeals to me again. In the meantime, there are a handful of other runners that match or surpass my skill in the game that will likely challenge the record very soon. The record could be improved at any time."
In total the Virginia gamer has broken the record six times in two years, lowering the time from 4 min 57.627 sec which he set in October 2015 to this year's time of 4 min 56.528 sec.
And he has some advice for anyone wanting to take on the game.
