Time for a look at some truly impressive gaming skills, as a speedrunner has managed to beat the whole of GTA 5 without taking any damage: and he did it all in nine hours.
The feat was achieved by UnNameD, who uploaded a three-part video of the run to YouTube on Sunday. According to the description this was UnNameD's 48th attempt at completing the run, in which he had "1HP, no Trevor ability, no armours, 0 deaths". UnNameD used the One Hit KO mod to complete the run, which kills the player immediately if they take any form of damage. That includes rogue cars, stray bullets, or even falling a little too hard on the floor.
As for the nine-hour time posted by UnNameD, it takes the average player about 31.5 hours to beat GTA 5's main story, while top-tier speedrunners can do it in about 3.3 hours with mission skips. They don't have to worry so much about taking damage, however.
