It is tempting to construct a narrative, about the Portal 2 co-op bots Atlas and P-Body, breaking out of Aperture Laboratories. Maybe they hopped a bus to the big city. And maybe that big city went by the name of Liberty.
Youtube user and videogame modder taltigolt has uploaded a video of a mod by fellow modder Indirivacua that brings the bots and Grand Theft Auto IV together like cookies and milk. In five incredibly amusing minutes, the hapless little test bots steal taxis (and, at one point, a luxury vehicle), mow down pedestrians, commandeer a motorcyle, blow up city blocks and parachute off skyscrapers.
It's fun to imagine that just like Niko Bellic, the American Dream didn't pan out for the little bots the way they hoped it might, instead turning them into hardened criminals.
The whole thing has a sort of Midnight Cowboy quality to it, but with way more explosions and a happier ending.
If you want to bring Atlas and P-Body to Liberty City, the mod is available for download here.
