GTA Online has a hacking problem. Slash feature.
If you play GTA Online you've probably encountered hackers. Despite Rockstar's fierce policing, all sorts of cheats and trolls make it through the net, and veteran players have become accustomed to the weird and annoying behaviours of these nefarious types.
The first time it happens, though, it can be terrifying. Nick Breckon of the popular Idle Thumbs podcast experienced one such incident, and has released the video for posterity.
It's pretty funny, but gosh - imagine if this happened in the dead of night, and you had no idea what was going on. It's almost creepypasta material.
Video games are weird and wonderful, even - or maybe especially - when they don't work as intended.
