As the saying I just made up goes, if you can play it, you can speedrun it. This immediately holds true for Arkane Studios' Prey, which has been beaten in just eight minutes and 20 seconds. That seems fast. Warning: video contains spoilers.
Of course, to get through the game in less than ten minutes, you can't do it the fair way. As Tank War Room's Larryn Bell explains, you have to use the GLOO Cannon to "scale up walls and reach out-of-bounds areas outside the space station", otherwise, you'd spend hours doing to the way the designer's intended.
Considering the game hasn't been out that long, I'm sure we'll see lower times over the course of the next few weeks and months... and eight minutes is already pretty quick.
