Chris Livingston has already extolled the virtues of Grand Theft Auto 4's amazing #WatchDogsIV mod. For the uninitiated, it brings Watch Dogs style environment hacking into GTA's Liberty City. For a full round-up of what it enables, head on over to Chris's Mod of the Week post. For a small look into the type of chaos it supports, stay right here.

Being a child, the first thing I did on loading the game was to start a traffic jam:



So far, so Watch Dogs. But the Traffic Lights prompt reappears quickly after. I wonder...



Yup. Multiple prompts means multiple pile-ups, meaning I can stack this thing right up. Time to do that. Everybody, welcome to the jam.



What makes this so funny other than the obvious is that the cars in the crash accelerate every time I hit the prompt, pushing them deeper and deeper into the ultra-jam. Also, as you can see from the picture above, a man has spontaneously combusted.

That's probably not a good sign.



Nope, definitely not a good sign. We have reached peak jam. It is jam-a-geddon.





Perhaps unsurprisingly, this tanked the game's framerate. My rig battled on regardless to bring you this dramatic re-enactment.



You can download #WatchDogsIV from here, and you probably should.
